Virtuoso Video Diary: Multi-Technology Simulation—The Good has Changed for Better

If you have multiple circuits designed with different process technologies on a single chip, it seems very likely that you have used our Multi-Technology Simulation (MTS) feature to simulate them. And, if you have used it recently, you would have noticed that the Multi-Technology Mode option through which you used to enable the feature is no longer there on the Choosing Simulator form. Where has it gone? Well, it has not only found a new address, but a new name too.

New address: MTS Options Form
New name: Enable locally scoped models and options (MTS)

We have also changed the way MTS settings are saved. Earlier, they were saved in a configuration view, but now the MTS settings are saved in the test state, thereby enabling you to set up MTS for each test independently.

Model files and process parameters can now be locally scoped at the instance level. Earlier, this was possible only at the cell level. That makes the MTS feature truly local, justifying its new name. By default, these settings are copied to the instance from its cell. You, however, have the flexibility to define different model files and process parameters for an instance from those defined for its cell.

With all the changes MTS has undergone, you would certainly agree that an otherwise-good feature has only changed to become even better.

 To know more about the other enhancements made to this feature, watch the Multi-Technology Simulation (MTS) with Local Scoped Models video on Cadence Support portal.
