Automatic Recognition of MOS Instantiations
in TSMC Libraries
Eldo accepts MOS devices instantiated in TSMC libraries using subcircuit instantiations.
TSMC provides two sets of libraries:
• MACRO library—where MOS devices are represented by subcircuits, and hence uses
the letter ‘X’ in the netlist for instantiation. This is the MACRO approach.
• TSMC Modeling Interface (TMI) library—where MOS devices are instantiated
normally as MOS devices.
The same netlists can be used when switching from one library to another. If Eldo cannot find a
subcircuit definition with the expected name, but finds a .MODEL definition, it converts the ‘X’
instance into a normal MOS instance.

Running Multiple Runs
The .MPRUN command runs multiple simulations on one multi-processor machine, or on many
machines.
Notes
• When the simulation of the netlist is very short (for example less than 1s), the .MPRUN
feature is not suitable because most of the simulation time is spent collecting results.
One solution is to use USE_LOCAL_HOST=NO, but for very short simulations this is
not enough, and total simulation times are similar with or without the .MPRUN
command.
• In all cases, Eldo will warn you if a host cannot be used.
