Title: defining inputs to schematic using verilog
Post by rgnanadavid on Feb 3^rd, 2007, 6:05am

I have designed a register file using cadecne spectre IC 5033. It is becoming difficult for me to define the input vectors in the GUI. can i use verilog to feed the inputs to my schematic and use the same verilog to dump out the results from my design.. thanku

In recent versions you can drive spectre using VCD (Verilog Change Dump), EVCD (Extended Verilog Change Dump) or Vector files. These are digital stimulus files. However, you'd need to be using spectre from MMSIM60 or MMSIM61 (if my memory is correct), and also an IC5141 version to provide this via the Setup->Environment form.

You can't use Verilog code (assuming this is normal digital Verilog) to drive spectre, since spectre is an analog simulator. If it was Verilog-A, you'd be OK. If you're using a mixed signal simulator such as AMS Designer (or the older spectre-verilog mixed-signal simulator) then you could use Verilog stimulus...
