Florent Kermarrec e946f6e453 fhdl/verilog: do not use initial begin in _printinit (not accepted by all synthesis tools ex: Synplify Pro does not accept it) 2015-03-16 23:47:07 +01:00

Sebastien Bourdeauducq 135a4fea25 fhdl/verilog: fix representation of negative integers 
Give the explicit two's complement representation for the given bit width.

This results in less readable code compared to using unary minus,
but fixes a bug when trying to represent the most negative integer.
