d6c4dfb902 Ensure fid() calls make_id() for consistency; tests/simple/dff_init.v fails 
Mark dff_init.v as expected to fail since it uses "initial value".

171c425cf9 Fix FIRRTL to Verilog process instance subfield assignment. 
Don't emit subfield assignments: bits(x, y, z) <= ... - but instead, add them to the reverse-wire-map where they'll be treated at the end of the module.
Enable tests which were disabled due to incorrect treatment of subfields.
Assume the `$firrtl2verilog` variable contains any additional switches to control verilog generation (i.e. `--no-dedup -X mverilog`)

fc1c9aa11f Update cells supported for verilog to FIRRTL conversion. 
Issue warning messages for missing parameterized modules and attempts to set initial values.
Replace simple "if (cell-type)" with "else if" chain.
Fix FIRRTL shift handling.
Add support for parameterized modules, $shift, $shiftx.
Handle default output file.
Deal with no top module.
Automatically run pmuxtree pass.
Allow EXTRA_FLAGS and SEED parameters to be set in the environment for tests/tools/autotest.mk.
Support FIRRTL regression testing in tests/tools/autotest.sh
Add xfirrtl files to test directories to exclude files from FIRRTL regression tests that are known to fail.

6378e2cd46 First draft of Verilog parser support for specify blocks and parameters. 
The only functionality of this code at the moment is to accept correct specify syntax and ignore it.
No part of the specify block is added to the AST

dbfd8460a9 Allow $size and $bits in verilog mode, actually check test case 2017-09-29 11:56:43 +02:00
Udi Finkelstein
e951ac0dfb $size() now works correctly for all cases! 
It seems the issues was that AST_MULTIRANGE is converted into a multirange_dimensions[] array on the AST_MEMORY node directly.

6ddc6a7af4 $size() seems to work now with or without the optional parameter. 
Multidimensional arrays still don't work. I suspect the problem is that the array is flattened into a 1D array before $size() is evaluated.
