ERROR (305) while importing netlist into Allegro

PROBLEM:
When I import the Capture design netlist into Allegro PCB Editor, I get “ERROR(305) Device/Symbol check error detected”. The component pin count does not match the Allegro PCB Editor footprint. Why?

SOLUTION:
There are two possible solutions to this problem.

Solution 1:
In OrCAD Capture, find the component giving problem. For example, let’s assume that you have a schematic, which has seven pins defined, but the Allegro PCB Editor footprint was a SOIC8 pin device.

You can assign a property in Capture that will let you leave the Capture symbol as it is with 7 pins. To do this:

1. Right-click the symbol and select Object Properties to open the Property Editor.
2. Create a new property called PINCOUNT and assign a value, which equals the Allegro footprint. In this case, it is 8.

Note: Make sure that the PINCOUNT property is defined in the allegro.cfg.

3. Create an Allegro netlist.
4. Import the netlist in Allegro PCB Editor. No errors are generated for this device.

Solution 2:
Manual Name
OrCAD Capture FAQ
1. Open the symbol.
2. Edit the part and add a new NC pin called 8.
3. Update the symbol and redo the netlist.
4. Import the netlist in Allegro PCB Editor.
