  • Eagle VS Altium-What Is The Features And Differences

    June 20, Update A lot has changed after I initially created this post. Therefore I am updating this article so you have more accurate information. My answer is … it depends. Altium is a complete package — you have everything in one place from schematic, libraries, pcb, output documents.

    It is also very intuitive and user friendly. Or, if your team is bigger, OrCAD can make sense. Disadvantage of OrCAD is, that you may need some time to get used to it and they still need to improve some stuff. But I know they are working on it … Still, if you have for example 3 engineers, that would be like 6k vs 30k for buying the software … big difference, and I would go for Cadence, even it is not as nice and easy to use as Altium Altium has some cheaper options like CircuitStudio, but I would not go that way.

    This will cost you more money, but everything works together e. Cadence simulations are really good, Altium is not good in simulation. Also, a lot of big boards have reference designs in Cadence, this can save you a lot of time and money.

    I talked to some engineers who use Altium, because it helps them to work closely with mechanical guys. I was initially impressed with the EUR or it was something similar for the Orcad. The Orcad Professional price was comparable with Altium Designer. And if your company grows and you do more and more complex boards, you may very easily find the limits of Orcad Professional. So, if you want to use the Orcad PCB Designer for all your future designs and you are sure you are not going to design any boards with differential pairs or memories — go for it.

    If you are planning to do layout professionally and you are planning to grow and design more and more complex boards, be sure you have considered all the option and made the right decision.

    Note: This is not an advert for Altium. Of course, this may change soon — if it does, be sure I will write and article about it. I am very suspicious, that the company wants us to become depended on their online services and later pay high subscriptions for using them this is my personal opinion — and hopefully I am wrong :.

    Altium, PADS and Orcad Design Migration in CADSTAR

    Here we get to define the via parameters as given below: Defining the size and shape of via Net — utilize the drop-down list to choose the net that contains the via.

    Every net for the board design that is active will be displayed in the drop-down list. In case there is no net, click the assign net button to open the dialog for the net name. Here you can choose the required net in the design workspace by typing the net name.

    Name — when one or more vias are selected, the via name is displayed by clicking the drop-down. All vias implemented on the board must be from the via spans defined in the layer stack. Template — this displays the current template that is used for the via.

    To select another template, the drop-down menu can be used. In case there is a library associated with the template, it is displayed as well. Library — this displays the via template that is stored in the current library. PvLib , it will include the library name in the specified field. After placement, the icon is enabled, indicating that the placed via properties are defined in the library and are not editable anymore. If the icon is not enabled, the contents can still be edited. Propagational delay — this field displays the propagation delay, which is the period of time taken for the signal head to move from the sender to the receiver.

    You need to change the field value to alter the via position relative to the current origin. The field value can be added in imperial or metric units and can be changed according to the requirement.

    Units setting in the other region of the properties panel in the board mode can decide the default units when they have not been specified. Y second field — This is for the Y position of the via center, and the same procedure can be followed as mentioned above.

    Hole information The fields that let you define the via hole parameters are as follows: Hole Size — this field is meant to display the current hole size of the via. This parameter specifies the hole diameter in mm or mils to be drilled during manufacture. The hole shape can be circular, square, or slotted and the hole size can be set from 0 to mil. For mechanical holes copper free the hole size can be set to be larger than the via.

    You can edit the field value to change size according to requirements. The unit settings are identical to the one explained for the X Y fields. Tolerance — The fits and limits of the board can be decided by setting the hole tolerance attributes. You can specify the minimum and maximum tolerances for the hole and there is no particular default hole tolerance value in Altium Designer.

    How do you set the size of a via in Altium Designer? The size and shape of the via are defined as follows: Simple — this option is used to choose a simple via. Diameter — enter the required diameter of the via in this field.

    The via diameter will be the same on every layer. Thermal Relief — select this box to introduce thermal relief required for mitigating heat conductivity. Setting via size Top-Middle-Bottom — this option can be used to select varying diameters for the top layer, internal signal layers, and bottom layer. Displayed layer s — click a displayed layer to set the via dimensions for that particular layer. The layer that is selected will be highlighted.

    Diameter — click the drop-down and enter the required via diameter for the selected layer. Thermal relief — the process to set this variable is similar to the one in simple via. Defining a via type The Z-plane or layer-spanning requirements of every via type can be defined using the via types tab.

    This tab does not define the size properties of the via, such as the diameter and hole size. You can define the Z-plane layer-spanning requirements for every via type here, that will be needed for the design. When you open the tab for via types, it will include a single, thru-hole via type.

    A two-layer board will have the default via named as Thru The convention here represents the via type and the first and last layers that the via spans. This default thru-hole span cannot be deleted. To edit the selected via type, you can use the layer stack manager mode within the properties panel. In case the panel is not visible, you can click the button at the right portion of the application to enable the same. To add via type, click the add button, followed by selecting the layers that the via type spans in the properties panel.

    The newly defined via type will have a naming convention as mentioned above, with the hole type and the first and last layer numbers.

    Based on the layers chosen, the software will automatically identify the via type buried, blind, and thru and name the via type systematically. The span of the via type can be defined by configuring the first and last layer settings. For the mirror option to be available, you need to enable the stack symmetry option in the board section of the properties panel.

    This mirror option is useful when you require a mirror of the current via that will span the symmetrical layers in the layer stack. Save the stack-up to update the changes in the PCB Editor. Graphical editing It is not possible to graphically modify the properties of a via other than the location. To move any via along with the linked tracks, click and hold, then move the via.

    The linked routing will remain connected to the via while moving it. Non-graphical editing The following techniques of non-graphical editing are available: Properties panel Via properties can be edited using the properties panel in PCB Editor which enables editing of all items selected in the workspace. The Tab key can be used to access the panel during placement.

    To access via properties of a placed via: Double-click on the via. Right-click on the via then choose properties from the context menu. If the Properties panel is already active, click once on the Via to choose it. Editing multiple objects In the properties panel, multiple objects can be edited using the property settings for any objects that are selected.

    Multiples of the same object type can be chosen manually through the list or filter panel or even the find similar objects dialog. Display of blind hole via with start and stop layer Via colors Using the view configuration panel, you can configure the via colors. The via copper ring is shown in the multi-layer setting in the layers section. The via hole color is available in the via holes setting in the system colors section. One can also disable the hole display by toggling the desired settings.

    Display of through-hole via How do you select all vias in Altium Designer? You can work with placed vias vias that have already been defined as follows: The layer numbers in the span of the via can be shown within via types by toggling the via span display. This is available in the view options tab within the view configuration panel. Working with stacked vias: While working with stacked vias, to form a continuous connection, click and drag the stack to move it as a whole, with the attached routing.

    To choose the uppermost via in the stack click once on the required via. To select the other vias in the same stack, use single clicks without moving the cursor. To choose all vias in a particular stack, click once to select one, then press tab to apply the selection to all vias in the stack.

    Net information Net information is a group of parameters that are used to identify and specify a net and are as follows: Net name — the name of the selected net. Net class — the name of the selected net class. Total length — the total signal length is the precise calculation of the total distance between nodes. Placed objects are evaluated to resolve overlapping or stacked objects, wandering paths within pads, and also the via length that is included.

    The pin package length is also included once it has been defined for pads. Total delay — the delay of the segments in the total length that have been routed.

    This includes the via and pad propagation delay values when they are defined for the vias and pads. Selected length — the total length of the selected object s. Selected delay — the total delay of the selected object s. Net Information How do you set via design rules in Altium Designer? Here we will cover the routing via style design rule to define a via.

    When you place vias during interactive routing, the size properties are defined by the applicable routing via style design rule. To place vias using the design rule, there is a set of via-related query keywords that can be used in the scope of rules.

    Via style design rule.

    If not, then then DipTrace is probably your best choice, unless you need to collaborate with other engineers. GROUP 3 — Engineer entrepreneurs — If you have prior experience designing electronics or wish to learn how then you may be better off designing your product yourself.

    Or at least as much as possible. DipTrace is definitely the way to go for you! No need to waste hours reading a boring manual with DipTrace. Eagle is the clear loser in regards to being intuitive to use. In fact, it will probably be many weeks before you are actually comfortable with it, if ever. It is only half the price of Eagle, or only an eighth the price of Altium. DipTrace also has a low barrier to entry because you can begin with their low-cost Starter version and upgrade your way up as needed.

    Altium is the clear winner for this criteria, with Eagle in second, OrCad in third place, and DipTrace coming in last. All four packages come with huge libraries of components.

    Because they are so popular, Altium and Eagle are probably the winners for this criteria because component manufacturers are more likely to provide a component library for one of these two packages.

    Honestly, it was horrible software that was very confusing and difficult to use. So it also cost an incredible amount in lost design time from engineers. In general, it took new designers several months to get really efficient in its use. Not so with DipTrace. At the other extreme is Eagle which will cost you weeks of lost design time.

    One for schematic entry, one for PCB layout, one for creating new components, and one for creating new PCB landing patterns. All vias implemented on the board must be from the via spans defined in the layer stack.

    Template — this displays the current template that is used for the via. To select another template, the drop-down menu can be used. In case there is a library associated with the template, it is displayed as well. Library — this displays the via template that is stored in the current library.

    PvLibit will include the library name in the specified field.
