Svtv-run

Run an SVTV and get the outputs.

Signature

(svtv-run svtv inalist &key (skip 'nil) 
          (include 'nil) 
          (boolvars 't) 
          (simplify 'nil) 
          (quiet 'nil) 
          (readable 't) 
          (allvars 'nil)) 
 
  → 
res

Arguments

svtv — Symbolic test vector created by defsvtv.
    Guard (svtv-p svtv).

inalist — Alist mapping input names to 4vec values.

skip — List of output names that should NOT be computed.

include — List of output names that SHOULD be computed.

boolvars — For symbolic execution, assume inputs are Boolean-valued.

simplify — For symbolic execution, apply svex rewriting to the SVTV.

quiet — Don't print inputs/outputs.

readable — Print input/output alists readably.

allvars — For symbolic execution, bind all variables, instead of skipping those not bound in the inalist.

Returns

res — Alist mapping output names to 4vec values.
    Type (svex-env-p res).

Svtv-run runs a simulation of the given symbolic-test-vector on the given inputs and returns the output values.

The input names and output names referred to above are the variable symbols used in the defsvtv form. For example,

(defsvtv my-test
  :inputs
  '(("clk"           1   ~)
    ("dwire"         _   _   _  dat  _)
    ("cwire"         _ ctrl  _   _   _))
  :overrides
  '(("inst.signal"   _   _   _  ov   _))
  :outputs
  '(("firstout"      _   _   _ outa  _)
    ("secondout"     _   _   _   _   _ outb))
  :internals
  '(("inst2.myint"   _  intl)))

In this STV, the input names are dat, ctrl, and ov, and the output names are outa, outb, and intl. See the section stvs-and-testing of the sv-tutorial for more examples.
