Patent ID: 7143019

Claim:
A method for associating instrumentation data with a hardware description language (HDL) simulation model within a batch simulation farm in which a simulation client communicates with an instrumentation server to process simulation data with respect to said HDL simulation model, said method comprising: delivering an instrumentation eventlist from said simulation client to said instrumentation server, wherein said eventlist contains instrumentation event information for said HDL simulation model; within said instrumentation server, computing a first digital signature that uniquely identifies contents of said instrumentation eventlist as being associated with said HDL simulation model; within said simulation client, collecting aggregate instrumentation event information resulting from simulation of said HDL simulation model, wherein said aggregate instrumentation event information is included within said simulation data; generating an aggregate instrumentation event packet that includes said aggregate instrumentation event information and further includes a second digital signature that identifies said aggregate instrumentation event information; delivering said aggregate instrumentation packet to said instrumentation server; and in response to said instrumentation server receiving said aggregate instrumentation packet: comparing the second digital signature with the first digital signature; responsive to the second digital signature matching the first digital signature, processing said aggregate instrumentation packet within said instrumentation server; and responsive to the second digital signature not matching the first digital signature, discarding said aggregate instrumentation packet.
