Martin Whitaker cf44f05cd3 Fix GitHub issue #324 - replace __CYGWIN32__ with __CYGWIN__. 
__CYGWIN32__ is not defined when building with the 64-bit Cygwin
toolchain. According to the Cygwin FAQ, __CYGWIN__ has been defined
since 1998, so this should still work for users on 32-bit systems.

Thoroughly fix parallel installation issues 
In PR #300, @xdch47 pointed out a stable way to fix parallel
installation problems.

This fix applied the method, thanks!

Martin Whitaker b91d5d1a82 vvp: recognise signed logic types when parsing class properties. 2019-12-23 09:48:07 +00:00
Stephen Williams 7f95abc6ab Make a pass at implementing cbAtEndOfSimTime. 
In Icarus Verilog, AtEndOfSimTime is practically the same as
cbReadWriteSync, since the latter is after non-blocking events
in Icarus Verilog.

Martin Whitaker 351a4e5f5e Improve vvp handling of excessively large shift distances. 2019-11-16 12:11:49 +00:00
Martin Whitaker 0a4cae2644 Fix vvp %shift instructions to treat right operand as unsigned. 
1364-2005 section 5.1.12 says "The right operand is always treated
as an unsigned number".

This fixes GitHub issue #283.

Martin Whitaker e6b0396e6f Makefile fixes. 2019-10-22 16:51:14 +01:00
Martin Whitaker a59b183bd1 Allow VPI modules to be loaded by multiple clients under Windows. 
The old scheme of linking the VPI modules with the vvp exports meant they
did not work when loaded by the compiler. Instead, let each client create
a jump table for the VPI routines and pass that to each VPI module as it
is loaded.

Martin Whitaker 3bdb50da29 Schedule UDP initial 0/1 assignments to occur during time 0. 
This allows any always processes that are sensitive to the UDP output
to start first. This fixes a time 0 race that was found in a Lattice
Semiconductor simulation library (reported on iverilog-devel).

If the initial value is 'x', propagate the value to the UDP output
before the start of simulation, to avoid unwanted update events on
the z -> x transition on downstream nets.

Martin Whitaker 866cc46915 Fix for GitHub issue #256 - don't use V as Makefile variable name. 
Some build systems override V on the make command line, wrongly assuming
it is the automake verbose option.

Martin Whitaker c383d2048c Fix initialisation of vvp symbol table values. 
In 64-bit Windows, an unsigned long is 32 bits, so initialising the num
member of the union did not properly initialise the ptr member. The num
member isn't actually needed, so eliminate it.

Martin Whitaker 8402696676 Fix VPI interface to APV objects. 
- type is vpiPartSelect, not vpiMemoryWord
- left/right range is for part, not full word
- index is not valid for a part select

The user will now get a sensible error message if they pass part of an
array word to $dumpvars (GitHub issue #230).
