corrected to correct the erroneous code some of these solutions may require the adjustment of more rtl module signals than others of these solutions the solutions that require the least number of adjustments would be considered the minimum symptom core there may be several minimum symptom cores if multiple solutions require the same number of adjustments to the rtl module signals when multiple cores exist redir framework 100 provides all of the possible minimal cardinality sets in addition the framework may suggest several possible fixes of the signals in the symptom core to help a designer correct those signals the framework 100 does not require a formal design specification and relies only on the availability of simulation test vectors moreover the framework 100 supports both combinational and sequential designs therefore it can be applied to any mainstream verification flow in addition it is more scalable than gate level approaches as indicated in our experimental results some example implementations can diagnose and correct multiple errors in design descriptions with thousands of lines of verilog code or approximately 100k cells after synthesis compared with state of the art gate level diagnosis techniques the redir framework 100 may be more than 100 u00d7 faster in most cases and may be able to diagnose more bugs with higher accuracy in contrast with existing rtl diagnosis methods that only provide potential error lists the redir framework 100 is significantly more accurate and can point out the.
