• “TSIM Syntax”
• “TSIM Input Files”
• “TSIM Output Files”
TSIM Overview
The TSIM program is a command line executable that takes an implemented CPLD design
file (VM6) as input and outputs an annotated NGA file used by the NetGen program. The
NetGen Timing Simulation flow produces a back-annotated timing netlist for timing
simulation. See the “CPLD Timing Simulation” section in Chapter 22, “NetGen” for more
information.
TSIM Syntax
Following is the syntax for the TSIM command line program:
tsim design.vm6 output.nga
design.vm6 is the name of the input design file (VM6) output by the CPLDfit program. See
Chapter 18, “CPLDfit” for more information.
output.nga is the name of the output file for use with the NetGen Timing Simulation flow to
create a back-annotated netlist for timing simulation. If an output file name is not
specified, TSIM uses the root name of the input design file with a .nga extension.
