Eldo Conversion Utilities
Utility to Convert .chi to .cir
Utility to Convert .chi to .cir
A standalone utility chi2cir converts an Eldo ASCII output (.chi) file into a netlist (.cir) file. The
resulting netlist file is independent of any libraries (no .LIB/.INCLUDE required), and all
information required for another simulation is inside the netlist file (providing that there were
no commands such as .NOTRC preventing the writing of the circuit description in the .chi file).
Usage
chi2cir [chifile cirfile]
Arguments
• chifile
Input filename, the Eldo ASCII output (.chi) file.
• cirfile
Output filename for the resulting netlist (.cir) file.
If no options are specified, the utility will prompt you for filenames.
Description
This utility could be useful to exchange testcases between user’s avoiding library dependence
and would also simplify the creation of different tests on the same circuit.
Once the circuit has been run once (to generate the .chi file), run this chi2cir utility to generate a
testcase from this .chi output to modify some parameters/options to re-run other simulations.
• The chi2cir utility does not handle references to Verilog-A model files or S-parameters
files.
• No provision is made for .ALTER statements for multiple simulation runs, only the first
simulation is taken into account.
Examples
chi2cir trigger.chi my_trigger1.cir
Once the original trigger.cir circuit had been run once (to generate the .chi file), running the
chi2cir utility on the trigger.chi ASCII output file generates a testcase file my_trigger1.cir.
Some parameters/options can then be modified in this testcase to re-run other simulations.
