steve 4de8ba489d Rewrite the cprop functor to use the functor_t interface. 1999-12-17 06:18:15 +00:00
steve 65ae92859c NetConst can now hold wide constants. 1999-12-17 03:38:46 +00:00
steve e96e8c62be NetESignal object no longer need to be NetNode 
objects. Let them keep a pointer to NetNet objects.

steve 4cfa3e4047 Support the creation of scopes. 1999-11-27 19:07:57 +00:00
steve fbf0bf1fb7 Whoops, created a signal with a duplicate name. 1999-11-19 03:00:59 +00:00
steve 2cce0ce238 Patch to synthesize LPM_ADD_SUB from expressions, 
Thanks to Larry Doolittle. Also handle constants
 in expressions.

 Synthesize adders in XNF, based on a patch from
 Larry. Accept synthesis of constants from Larry
 as is.

steve cb5fc54b5e Patch to synthesize unary ~ and the ternary operator. 
Thanks to Larry Doolittle <LRDoolittle@lbl.gov>.

 Add the LPM_MUX device, and integrate it with the
 ternary synthesis from Larry. Replace the lpm_mux
 generator in t-xnf.cc to use XNF EQU devices to
 put muxs into function units.

 Rewrite elaborate_net for the PETernary class to
 also use the LPM_MUX device.

steve b66e7b1713 Add the synthesize method to NetExpr to handle 
synthesis of expressions, and use that method
 to improve r-value handling of LPM_FF synthesis.

 Modify the XNF target to handle LPM_FF objects.
