The netlist compare algorithm is basically a backtracing algorithm.
|
||||
With ambiguous nets, the algorithm picks possible net pairs and
|
||||
tries whether they will make a good match. Following the deduction
|
||||
path for this nets may lead to further branches if more ambiguous
|
||||
nets are encountered. To avoid combinational explosion, the maximum
|
||||
branch complexity is limited to the value configured with this
|
||||
function. The default value is 500 which means not more than
|
||||
500 combinations are tried for a single seed pair. For networks
|
||||
with inherent ambiguity such as decoders, the complexity
|
||||
can be increased at the expense of potentially larger runtimes.
|
||||
The runtime penality is roughly proportional to the branch
|
||||
complexity.

<b>Note:</b> The resistance computation is based on a simple approximation. It computes the number
|
||||
of squares by tracing the perimeter of the "R" polygon. The perimeter length is separated
|
||||
in parts where the perimeter touches the "C" layer and parts where it does not. The number
|
||||
of squares is computed from the non-touching length divided by the touching length.
