spectre multithreading

I am using Cadence version 5.0.33, I want to use multi-threading option when doing spectreS simulation. Please help me...

Thanks!!!
 

Refer to "Spectre Circuit Simulator Reference" page 73

"... Currently, multithreading is only available for devices evaluation for BSIM3v3, and BSIM4.
Multithreading does not work with table model. If there is an instance of a primitive using table
model, multithreading would not be applied to all instances of that primitive.

Multithreading can be turned on/off by command line option, or by the multithread parameter
in the options statement from the input file. If both options are specified, command line option
will make the final determination on the number of threads to use..."

"... Currently, multithreading is only available for devices evaluation for BSIM3v3, and BSIM4..."

Does this mean that multithreading will not work if my design is Bi-CMOS?
(CMOS models are BSIM3v3, Bipolar model is bjt)

Thanks in advance...
 

It will work for the part that it can work. For your case, the CMOS model's equation can be done in parallel even though the BJT cannot. It should be noted that many things in circuit simulator are essentially sequential, so not much job can be done in parallel.
