Subject: Behavioral Compiler v3.4b Mysteriously Disconnected A Useful Net?
John,
While compiling a top level module in Bahavioral_Compiler that merely
instantiated two lower level modules (that were previously compiled) produced
a weirdness. A control net that is definitely functional within the design
(pre-synthesis) was disconnected between the two modules (it's an output
from one, and an input to the other). The dangling input was then tied
HIGH!? +%#@!! :-(
One suggestion from my local Synopsys team is that some problems with
boundary_optimization have been seen. Anyone with any ideas?
