Forum Post: Problem with EM/IR simulation: port name mismatch between SPF file and schematic netlist

Dear all, I encountered an issue when I tried to run EM/IR simulation. I basically followed the flow on "Voltus Fi GPDK45 DSPF RAK." I've tested this flow with a simple design and it works well. However, when I tried to run the simulation with my design, I received an error in the log file, which is ERROR (SFE-3287): Cannot run the simulation because the port number in SPF file does not match the port number in the schematic netlist. I guess the issue is due to the usage of the bus definition for the I/O port in the circuit schematic. Some ports are defined as buses; for instance XXX . The netlising generates the port name of XXX(0), XXX(1), and XXX(2) instead of XXX , XXX , and XXX . Therefore, it leads to the mismatch between the DSPF port and the schematic port as you can see in the log file. Does anyone know how to solve this problem such that the schematic netlisting creates the correct port name? Thank you in advance!
