Staf Verhaegen 92eb841f0a Value of properties can be expression. 
Example found in the 2007.03 Liberty Reference Manual that was also found
in the wild:

    input_voltage(CMOS) {
        vil : 0.3 * VDD ;
        vih : 0.7 * VDD ;
        vimin : -0.5 ;
        vimax : VDD + 0.5 ;
    }

Current implementation just parses the expression but no interpretation is done.

extract_reduce: Fix segfault on "undriven" inputs
 2017-09-14 22:36:25 +02:00
Robert Ou ab1bf8d661 extract_reduce: Fix segfault on "undriven" inputs 
This is easily triggered when un-techmapping if the technology-specific
cell library isn't loaded. Outputs of technology-specific cells will be
seen as inputs, and nets using those outputs will be seen as undriven.
Just ignore these cells because they can't be part of a reduce chain
anyways.

C-Elegans 84f9cd0025 Optimize compares to powers of 2 
Remove opt_compare and put comparison pass in opt_expr

assuming a [7:0] is unsigned
a >= (1<<x) becomes |a[7:x]
a <  (1<<x) becomes !a[7:x]

Additionally:
a >= 0 becomes constant true,
a < 0 becomes constant false

delete opt_compare.cc
revert opt.cc to commit b7cfb7dbd (remove opt_compare step)
