spectre.dc saves array lines as out_0 not out<0>

yayla

 Hi,

I tried to save final value using "write" box in DC Options. I am saving spectre.dc file and trying to use it for next simulation but I have noticed that when I want to save buses like out<3:0>, it saves out_0, out_1 ... not out<0> or out<1> so that Cadence couldn't figure out those wires and gives unknown net warning. When I have changed those buses to <>, I can run the simulation. Do you know how to save spectre.dc as out<1> rather than out_1.

 

Thanks,

yayla

  • Ok, well there's a lot of information there that you didn't provide originally. Also, you didn't say which version of the tools you're using. It's quite possible that there's something in one of the PDK setups that is altering how the mapping is done when netlisting, and this is different between the two PDKs. In fact that's pretty much the only explanation as to why you might be getting different mapping in the two different cases.
