Stephen Williams 29ac33493e Add support for a command line dumpfile option 
The -dumpfile=<path> vvp extended argument sets the default nanme to use
for the various dumpers. If this flag is not given, the default is "dump".
The $dumpfile system task overrides the default or this command line flag.

This commit also factors out all the dumpfile selection code for the various
dumper implementations.

Jevin Sweval e80746c50f Fix sscanf overflows 
Without this fix, ivlh_textio was failing at step 11 where the time is read from the file. This was because clang happens to put period directly after the units buffer on the stack. sscanf writes the terminating NUL overwriting the low byte of period, which is 100, so it returns 0.

Example clang warning fixed:

warning: 'sscanf' may overflow; destination buffer in argument 4 has size 2, but the corresponding specifier may require size 3 [-Wfortify-source]

Stephen Williams 6564f55219 Fix vcd dump of real value parameters 
Parameters with real values are possible in Verilog, but not in the VCD
format, so lie a little and call them "real" objects. Otherwise, we can
treat them like constants and it works out, at least for gtkwave.
 2022-05-21 10:13:27 -07:00
Stephen Williams 73f40f73b0 Add parameters to fst dumps 
Add support for parameters (constants) in fst dumps. And while we are at
it, factor out some of the declarations shared with sys_vcd.
 2022-05-16 20:47:32 -07:00
Stephen Williams a1485906ca Add parameters to vcd dumps 
Writing parameters into VCD files makes the values available to waveform
tools. This can be done easily enough by writing out a $dumpadd section
at the beginning of the file that sets the parameter values. We don't need
to track the values over change, because by definition they do not change.

This changes the typical vcd output as well, so a few of the regression tests
need to be adjusted to account for this.

Also, while tracking this down, found and fixed the vvp/README.txt documention
for the .param/x records.

Martin Whitaker 94e09ec473 Use explicit 32-bit integers in random number system functions (issue #661). 
This simplifies the code by making it independent of the size of 'long', and
fixes the behaviour of urandom_range when the upper limit is > 0x7fffffff.

Martin Whitaker 8e4cc8e887 Use GNU make pattern rules to handle multiple file output from bison. 
With a pattern rule, the recipe will only be executed once, even when
the rule has multiple targets. Using this to handle the output from
bison is included as an example in the GNU make manual.

This fixes the makefiles so that bison-generated header files will be
regenerated if they are deleted.

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.

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 542fe2cf77 Enable checks for VPI const-correctness. 
Note we only want these enabled when building the compiler and runtime
binaries. If we included the ICARUS_VPI_CONST definition in the global
CPP_FLAGS, that would propagate to the flags used by iverilog-vpi, so
would affect compilation of user VPI code.
 2018-10-06 11:48:19 +01:00
Martin Whitaker b066a5815e Allow %c format to output null characters (GitHub issue #209) 
Currently $display et al. output nothing when the expression
corresponding to a %c format specification has the value 0. As
Verilog provides no other way to write raw bytes to a file, we
should allow 0 values to be written. Other simulators allow this.
 2018-09-29 21:22:17 +01:00
Martin Whitaker 0d494da702 Further fixes for const-correctness.
