steve c339dc4bbc Remove last bits of relax_width methods, and use test_width
to calculate the width of an r-value expression that may
 contain unsized numbers.
2006-11-04 06:19:24 +00:00
steve 71faebd6df Make elaborate_expr methods aware of the width that the context
requires of it. In the process, fix sizing of the width of unary
 minus is context determined sizes.

steve 8f2d679c8a Unify elaboration of l-values for all proceedural assignments,
including assing, cassign and force.

 Generate NetConcat devices for gate outputs that feed into a
 vector results. Use this to hande gate arrays. Also let gate
 arrays handle vectors of gates when the outputs allow for it.

of single bits. Make the ivl, tgt-vvp and vvp initial changes
 down this path.

steve bf72f39fe9 eval_const uses scope instead of a string path. 2001-11-07 04:01:59 +00:00
steve e35ed6e91c Change the NetAssign_ class to refer to the signal
instead of link into the netlist. This is faster
 and uses less space. Make the NetAssignNB carry
 the delays instead of the NetAssign_ lval objects.

 Change the vvp code generator to support multiple
 l-values, i.e. concatenations of part selects.
