I have a design consisting of 32 bit input pin sitimulis problem

ahmed osama

 I am using spectre as simulation tool , my design have 32 bit input pins how i can assign this bits with values

I use vector file but it works fine with single bit , when i increase radix more than 1 it fails

I use sitimulis file but it also fails 

what is the most effective way to test 32 bit input pins in spectre 

Thanks

  • That would rather suggest that your circuit is not working properly. If the input signals are the right shape but the outputs are not what you expect, I don't see how giving the stimulus in a different way is going to magically make the circuit start behaving?

    The vector file approach should be fine. That said, none of your graphs matched the example vector files you gave, so I really don't know if this is user error or circuit error. It certainly does not appear to be an issue with the tools.

    Kind Regards,

    Andrew.
