Library Multi-Technology Simulation Mode (lmts)

Description

Activate TMI Library Multi-Technology Simulation mode. Under this mode, multiple TMI shared libraries are allowed to be simulated in the same netlist.Please make sure that all TMI shared libraries are included in their own sub-circuit in TMI MTS simulation.

Here is an example of a system consisting of blocks designed with different TMI shared libraries:

subckt subckt1 ( in out )
include "TMI_PDK_1.scs" section=sec1 
.......
ends subckt1
subckt subckt2 ( in out )
include "TMI_PDK_2.scs" section=sec2 
......
ends subckt2

In the inventory of log file, you will see the following primitives:

Circuit inventory:

subckt1_tmibsim4      10      subckt=subckt1
subckt2_tmibsimcmg    10      subckt=subckt2

Features Supported in Spectre

The TMI MTS flow has been constantly enhanced and qualified for different Spectre features and analyses. Refer to the following table to learn about the features supported in this flow.

This table will be updated every time a new feature is qualified in Spectre.
