151 Threads found on edaboard.com: Run Spectre Simulation Cadence
I have a downloaded a PSpice model file (in .lib) from On Semiconductor.
I am wondering how to run spectre simulation in cadence with this file. For the same diode, there are .sp2 and .sp3 models are available as well. Am I using the right one (.lib) for spectre simulation?

I have only hspice model file and need to run simulation. Since I'm familiar
with spectre and wanna use it to run. But I don'w know if I may do with
hspice model, or need I deal with the model file? How to do it? Thanks for

I want to run a simulation using cadence(icfb). The simulation should show time transient result with a time varing resistor value. Basically, I want to assign the value of resistor as res = sin( w* time) + some offset. Is there any way to do this?
The value of the resistor should vary along with the time (...)

Why not using spectreVerilog run the simulation. it can also seperate digital and analog part to run a mixed-signal simulation. you can refer to openbook.

run the simulation,
Hit op button - little popup will (should) appear. Select on schmatic the device you are interested in and the in pulldown menu list in the pop-up select gm.
Then hit plot in calculator.

cadence Analog Artist has an option "Corners" for a corner analysis.
It works like a more complex parametric analysis.
You need to defind a path for your corner models and run Corners Analysis.
As a result you'll get a set of curves for different corners.

What's your digital part seems like? Do you write it with verilog. If this right,you should setup your digital part in "behaviral" view and run with "spectreverilog",Or you can run with spw. The process is quite similar.
Hope this helpeful.

spp only converts the format of the netlist and it can not convert spice model to spectre model. This is why foundries usually provide both hspice and spectre models.

There is perl script provide by cadence in converting the spice netlist to spectre netlist.
By the way, TSMC always provide digital/analog library pdk to designers. So what you do is use include the spectre model inside tsmc pdk to run the simulation.

I don't use Pspice but my approach for doing this sort of thing is to change the obvious syntax differences and then run a simulation. Then try to work out what the error messages mean and fix them. Comparison with a working Pspice model in a similar technology would help. For example - how fingers are handled in the symbol & template.
