preproc.py script from another project. Had to further develop it to get around the amazingly complicated preprocessor usage in the scmos subdirectory. Needed to add handling of parameterized definitions; could not figure out how to align the syntax used in scmos/extract_template with any consistent syntax. Gave up and rewrote some of the contents of extract_template to avoid the more ambiguous usage. All of this is to support a completely deprecated scmos.tech. However, it does avoid both the M4 and cpp preprocessors altogether. Also did auto-detection of python3 in the configure script for use of the preproc.py preprocessor, and applied the same preprocessor to the macro definitions.

This is for HP's CMOS26B 1.0 micron CMOS Bulk Process.

|
All parameters are defined based on HP's general process
|
|
specifications (GPP). Sidewall fringing was taken from
|
|
Ersatco fictitious process (johnson,jouppi).
|
|
|
|
Upwards fringe caps (eg poly-->m1, poly-->m2) are computed
|
|
by the program scaleCap by using the Skurai/Tamaru formula
|
|
based on the known capacitances.
