Cary R	ebdf4e478a	Rework more compiletf and calltf routines in the vpi directory. ... This is a major rework on the sys_fileio routines. They now have improved compiletf routines and the calltf routines are now standardized. Along the way a few bug were fixed as well. Some updates to other vpi files as well. I changed the order of the $fputc() arguments to match C and the rest of the system functions like it ($fungetc, etc.). I recently fixed $fungetc() so I'm assuming the $fputc() needs the same fix. It's an Icarus specific function.	2008-06-14 20:13:52 -07:00
Stephen Williams	bbc80a84a6	Rename $log to $log10. ... Verilog-2005 defines the base-10 log function to be $log10. This makes sense because in C the log() function is the natural log. So add the $log10 function. Since there may be legacy code that uses the $log function, leave it defined, but we should consider at least printing a warning when the $log function is used.	2008-05-03 18:29:52 -07:00
Stephen Williams	f5263c9447	Add the va_math module and constants.vams include file. ... The va_math.vpi module implements systen-function versions of the Verilog-A math functions. This library was contributed by Cary R. Also add the constants.vams include file. This is pretty much direct from the Verilog-AMS LRM.	2008-04-29 21:20:39 -07:00
