Using Hspice Tech Files in Cadence

[easytarget]

Hi,

Is it possible to use an Hspice technology file in Cadence, so I can work in a graphical environment, rather than Hspice? I know about converting hspice tech files to Spectre, but I don't know where to go from there. Thanks for your help.

Firstly, Cadence is the GUI in the form of dfII(Design Framework II). SPICE and Spectre are simulators. Of course, you can have the Cadence interface and work in HSPICE. Synopsys and Cadence have developed plug-ins. Mostly people in the industry, use Cadence with HSPICE as simulator.

Another way is to use HSPICE models and convert them in Spectre. Use the following command.
spp -convert -hspcompatible <hspice file> <spectre file>.

You can convert all your HSPICE models to Spectre models. Also you can use the .sp files to run in spectre. Spectre has compatibility with SPICE files as well.

I hope it helps................

Another question

Thanks for your help. I have another question please:
If I choose: Use Hspice Netlist Reader(spp), in the analog environment, do I still need to convert my hspice tech file to Spectre? Thanks.

Definately you can use that option. Then you do not have to manually convert any file. But there could be some problems with the SPP parser. You would have to make very minor changes. That is the reason why I would suggest running Spectre from console.

Thanks Vamsi Mocherla.

how about convert spectre models to hspice models?

I just tried it your way and it worked, I typed:

spp -convert -hspcompatible < hspice_file > spectre_file.m

So I'll stick with this new spectre file it's safer. Thanks a lot for your help Vamsi Mocherla!!

Well, I do not know a way to convert Spectre models to SPICE models. But if you have some time, you can manually edit them because if you are using LEVEL 49, you can just see that there is only a change in the first couple of lines for each model.
