5 years agowrite_verilog: correctly emit asynchronous transparent ports.
whitequark [Tue, 29 Jan 2019 02:24:00 +0000 (02:24 +0000)]
write_verilog: correctly emit asynchronous transparent ports.

This commit fixes two related issues:
  * For asynchronous ports, clock is no longer added to domain list.
    (This would lead to absurd constructs like `always @(posedge 0)`.
  * The logic to distinguish synchronous and asynchronous ports is
    changed to correctly use or avoid clock in all cases.

Before this commit, the following RTLIL snippet (after memory_collect)

    cell $memrd $2
      parameter \MEMID "\\mem"
      parameter \ABITS 2
      parameter \WIDTH 4
      parameter \CLK_ENABLE 0
      parameter \CLK_POLARITY 1
      parameter \TRANSPARENT 1
      connect \CLK 1'0
      connect \EN 1'1
      connect \ADDR \mem_r_addr
      connect \DATA \mem_r_data
    end

would lead to invalid Verilog:

    reg [1:0] _0_;
    always @(posedge 1'h0) begin
      _0_ <= mem_r_addr;
    end
    assign mem_r_data = mem[_0_];

Note that there are two potential pitfalls remaining after this
change:
  * For asynchronous ports, the \EN input and \TRANSPARENT parameter
    are silently ignored. (Per discussion in #760 this is the correct
    behavior.)
  * For synchronous transparent ports, the \EN input is ignored. This
    matches the behavior of the $mem simulation cell. Again, see #760.

bugpoint: new pass.

A typical use of `bugpoint` would involve a script with a pass under
test, e.g.:

    flowmap -relax -optarea 100

and would be invoked as:

    bugpoint -yosys ./yosys -script flowmap.ys -clean -cells

This replaces the current design with the minimal design that still
crashes the `flowmap.ys` script.

`bugpoint` can also be used to perform generic design minimization
using `select`, e.g. the following script:

    select i:* %x t:$_MUX_ %i -assert-max 0

would remove all parts of the design except for an unbroken path from
an input to an output port that goes through exactly one $_MUX_ cell.
(The condition is inverted.)
