RODEO
Getting Started

To start Rodeo, you need to do the following things:

1. setup an environment variable PSCAN_TCL_LIB that would point to the Rodeo installation directory, e.g., in a C shell:

   > setenv PSCAN_TCL_LIB /foo/bar/pscan/lib/tcl/
   

   or in a Bourne shell:

   % set PSCAN_TCL_LIB=/foo/bar/pscan/lib/tcl/
   % export PSCAN_TCL_LIB
   

2. copy file .pscanrc.tcl from the Rodeo installation directory to your current working directory or create this file using any text editor. Initially, the file should contain only one line:

   source $PSCAN_TCL_LIB/rodeo.tcl
   

   The following should work fine at any UNIX box:

   % cat > .pscanrc.tcl
   source $PSCAN_TCL_LIB/rodeo.tcl
   ^D
   % 
   

   Do not include anything else in this file, since it may be overwritten by Rodeo! Also, be sure that this file is at least owner-readable. All customizations must reside in the files .pscanrc or ~/.pscanrc.
3. If you are planning to run Rodeo in a hierarchical model, you probably want to check if the files extern.map, xextern.map, script.map, and netlist.map reside in your current working directory and are at least owner-readable. You may also want to have customized mapping files.
4. Note that Rodeo will try to write to your current working directory, so make sure it is at least owner-writable.
5. And, last but not least: you must have a PSCAN executable file (e.g., dzSampl) and PSCAN data file that has the same name as the executable file with the .dat extension (e.g., dzSampl.dat).

Finally, Rodeo Tcl interpreter prompts you for the interaction. The prompt name as it appears in the command line is exactly the same as the name of your executable file. The command line has a built-in editor and a history buffer.

The interpreter recognizes any valid Tcl expression. An expression can spread over several input lines. Multiple expressions (e.g., in the body of a loop or of a procedure) be better separated with a semicolon:

dzSampl> proc dummy {foo} {
dzSampl>     set bar $foo;
dzSampl>     return $bar
dzSampl> }
