Add missing probabilistic functions and compiletf routines. Add the missing probabilistic functions and add compiletf routines for all the functions. The original calltf routines have been modified as appropriate. The base functions are straight copies from the standard. I have visually verified the curves with 5,000 points and they look correct. 2007-07-20 05:58:35 +02:00			`$random vpiSysFuncInt`
Declare $rtoi in system.sft instead of the sys_funcs table. The sys_funcs table should be left to those functions that are handled internally by the compiler. Really, the internal sys_funcs table is a legacy from the days before the compiler supported system function tables in the .sft format. 2008-01-17 21:48:02 +01:00			`$rtoi vpiSysFuncInt`
[PATCH] Implement System Verilog $urandom and $urandom_range functions. This patch implements the System Verilog $urandom() and $urandom_range() functions. There are no check to verify that $urandom_range is only given unsigned arguments. If you give it a negative value the bit pattern will be interpreted as a unsigned number. 2007-10-02 05:18:48 +02:00			`$urandom vpiSysFuncSized 32 unsigned`

Add $vvp_cpu_wordsize function This patch adds a new system function $vvp_cpu_wordsize. It returns the size of the underlying CPU word (long) in bits. This function can be used to write fully portable tests for the test suite. Other functions will be added as needed. 2008-05-07 04:00:32 +02:00			`$vvp_cpu_wordsize vpiSysFuncInt`
