public class EDIFNetlistComparator
extends Object

This is a helper class designed to compare two EDIFNetlists for differences. It can filter out differences introduced by Vivado by reading in the EDIF and writing out as a DCP. It can also generate a report file describing all the differences found. Please see @link DesignComparator to compare the placement and routing information of a design.

Field Detail

restoreBrackets

public boolean restoreBrackets

Setting this to true will attempt to account for legalized square brackets replaced by underscores around an indexed suffix on a Library name. For example, if the Library name was originally 'my_signal[4]' but in translation by Vivado was changed to 'my_signal_4_', setting this flag to true will attempt to find the square bracketed name equivalent

filterVivadoChanges

public boolean filterVivadoChanges

A netlist will undergo several changes when loaded via DCP vs. via EDIF. This flag attempts to account for the majority of those changes.
