• Importing EMPro circuit component definition from ADS

    Hi,      In EMPro, I usually create a circuit component definition (R,L,C) and assign ports to that definition and select 'not a port' option. However I need to do this every time and fo...

  • High Memory Requirement for PCB Simulation

    I'm exporting a PCB design from the Cadence Allegro to ADS 2017.1. The design is a 10 layer board with RF and digital section. I removed the digital fraction so only RF components are remained. Moreover I only export ...

  • 2 objects occupying the same space.

    Hi,   New to EPpro. I noticed I never get a warning or error message if I overlapped two pieces of different materials, such as AL and Cu, PVC and FR4, etc. The simulation goes on without a hitch. It'll sta...

  • Where can I find the EMPro's Core Dump file

    Hello, I have been running EMPro 2017 on RedHat 6 for a while. Recently, EMPro starts to crash fairly often. Most of the CAD Tools (such as ADS, Cadence, Matlab) generate a core dump file when they quit. Does EMPro a...
