I have searched ncsim in my installation DIR and can not find it. Thanks.

If using Cadence simulators, then yes, you'll need to install IUS (LDV is the old name for the stream, but there are no supported LDV versions these days).

The IC6 family does not contain any simulation at all (in earlier IC versions, such as IC5141, you had spectre, but that has been separated into a separate MMSIM stream, such as MMSIM70).

So, if you want to do circuit simulation or RF simulation, you'd need MMSIM70, and if doing mixed-signal simulation, you'd use IUS82 (for example) - MMSIM70 and IUS82 are the latest versions.

Regards,

Andrew.

Thanks Andrew:
But what confuses me is that MMSIM does have ncverilog and ncvlog and other ncxxxx files(except ncsim), Can I use these to do AMS simulation?

Thanks!

It only has a subset of the NC tools, and they are in a directory that is not intended to be put in your path - they're there for use by other parts of the tools, not for user-use.

So you should not use them (as you can see, there's no simulator - just the compiler, so you wouldn't be able to anyway!).

The only supported way of running AMS Simulation is to use the simulators from an IUS release.

Regards,

Andrew.
