Verifying Simulation Design Modifications

A computer program product comprising a computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed on a computing device, causes the computing device to:

• receive a modified description of the simulation design unit that failed to meet an expected physical property value during an initial simulation of the entire integrated electronic device;
• execute a simulation of the simulation design unit using a list of identified input signals from a trace file, wherein the trace file is generated during the initial simulation of the entire integrated electronic device, and wherein the trace file indicates state values for the list of identified input signals;
• determine whether the simulation of the simulation design unit fails to meet the expected physical property value;
• and
• responsive to the simulation of the simulation design unit meeting the expected physical property value, generate an indication that modifications made to an initial description of the simulation design unit are successful.

An apparatus, comprising:

• a processor;
• and
• a memory coupled to the processor, wherein the memory comprises instructions which, when executed by the processor, cause the processor to:
• receive a modified description of the simulation design unit that failed to meet an expected physical property value during an initial simulation of the entire integrated electronic device;
• execute a simulation of the simulation design unit using a list of identified input signals from a trace file, wherein the trace file is generated during the initial simulation of the entire integrated electronic device, and wherein the trace file indicates state values for the list of identified input signals;
• determine whether the simulation of the simulation design unit fails to meet the expected physical property value;
• and
• responsive to the simulation of the simulation design unit meeting the expected physical property value, generate an indication that modifications made to an initial description of the simulation design unit are successful.
