Can I co-simulate Hspice with verilogA components

[Su]

HI,

In my design, I need to look at output eyediagram which requires a
random number generator. In cadence I can find such component, but when
I put it in the schematic using HspiceS simulator, it does not work.

Could you please give me some idea on how to make this work?


thanks,

Yu

Firstly I don't believe HSPICE supports Verilog-A (I don't know for certain
since HSPICE is a Synopsys product, not a Cadence product). Even when HSPICE
eventually supports Verilog-A, the hspiceS netlister would need to be enhanced
to write out whatever statements HSPICE would need to include a Verilog-A
module. Most likely when (or if) that were to happen, it would be done with
the newer hspiceD interface rather than the obsolete hspiceS interface.

However, this is a moot point if HSPICE doesn't support Verilog-A yet...

Can you use spectre instead?

HI, Andrew:

Thanks for your reply. Since we have to incorporate a transmission line
model which only works in HspiceS, we can not use Spectre.
Do you know any way to generate a random sequence in HspiceS?

thanks,

Yu

Hi Yu,

Is the transmission line a "W" element in HSPICE? If so, spectre has the
"mtline" component which can be used as the W element...

I don't know how to generate a random sequence in hspice, sorry.

Andrew.

HI, Andrew:

Yes, it is "W" element.

thanks a lot for your suggestion, I will try mtline.
