Improve reporting detail of: Error: detail_place.tcl, 31 domain error: argument not in valid range

[oharboe]

Description

This problem appears to originate inside STA, but I have very little to go on to track down the error. I think it is a problem in my design, but I'm not able to find out where to set a breakpoint in OpenROAD to study it in more detail.

==========================================================================
detailed place report_check_types -max_slew -max_cap -max_fanout -violators
--------------------------------------------------------------------------
Error: detail_place.tcl, 31 domain error: argument not in valid range
Command exited with non-zero status 1
Elapsed time: 0:12.08[h:]min:sec. CPU time: user 11.57 sys 0.50 (99%). Peak memory: 1832188KB.

Suggested Solution

Some more clues in the error message so that it will be easier to set a breakpoint in the debugger to find out what is going on.

Additional Context

No response

I'm confused as I don't see anything in OR/ORFS that generates such a message. Assuming it is throwing an exception you can do 'catch throw' in gdb to stop when an exception is thrown.

The error comes from TCL.

test expr-22.5 {non-numeric floats} {
    list [catch {expr NaN} msg] $msg
} {1 {domain error: argument not in valid range}}

void
TclExprFloatError(
    Tcl_Interp *interp,     /* Where to store error message. */
    double value)       /* Value returned after error; used to
                 * distinguish underflows from overflows. */
{
    const char *s;

    if ((errno == EDOM) || TclIsNaN(value)) {
    s = "domain error: argument not in valid range";
    Tcl_SetObjResult(interp, Tcl_NewStringObj(s, -1));
    Tcl_SetErrorCode(interp, "ARITH", "DOMAIN", s, NULL);
    } else if ((errno == ERANGE) || TclIsInfinite(value)) {

It's related to various tcl number parsing issues, or out of domain functions.

Not that familiar with ORFS, but if this is the TCL code in your script, it looks in correct.

detailed place report_check_types -max_slew -max_cap -max_fanout -violators

Should be

detailed_placement
report_check_types -max_slew -max_cap -max_fanout -violators

@QuantamHD

The failure occurs in line 108 below:

xxx 2

I guess the question is if check_max_slew_limit is NaN

@oharboe Is make detail_place_issue creating reproducible test case?

@oharboe Is make detail_place_issue creating reproducible test case?

Yes, but not one that I can share. Moreover deltaDebug.py doesnt whittle down the lib and lef files for macros, which makes it trickier.
