Various checker enhancements, better Error messages #130

Open dmlockhart opened 9 years ago

dmlockhart commented 9 years ago

Throw an error if:

a signal is written in multiple behavioral blocks (not valid verilog) [ is this related to this? (#127) ]
a signal is written as .next in one block and .value as another
a signal is structurally written to by a connection and written to in a behavioral block
a signal is structurally written to by multiple connections
the .value/.next of an OutPort is written from outside a module
the .value/.next of an InPort is written from inside a module

Throw a better error message when:

s.connect( s.a, s.b ) fails because s.a is a port list and should be s.a[N]. Currently get:

AttributeError: 'list' object has no attribute 'nbits'
