DCO test using Verilog A "unexpected statement "{""

Yizhe Hu

Hi guys,

This is my testing code for DCO. I try to use spectre to do sp simulation.

Parametric Analysis change Vin every time, and then get the Dout (0V, or 1V thermometer code). Dout is used to control DCO Switch bank.

There is no problem with my Verilog-A, but spectre cannot detect "{", which appears in "parameter real valxx [64:0] = {0, 0...}."

How could I solve this? 

Could you give other testing method?

  • Please post the Verilog-A code as an attachment or in the post itself. A picture of the code isn't much help - I'm not going to sit and type it in again to try this out.

    Also, please post the instance line in the input.scs (line 156 - ideally lines either side of it just to make sure) so that I can see what the instance line looks like. The error is in the spectre netlist, not in the Verilog-A.

    By the way, posting my name in a reply or sending me a friend request won't get me to respond any more quickly...

    Thanks,

    Andrew.
