Prior to ModelSim release 6.2, the default mode for compilation and elaboration was for minimal optimizations, allowing for read/write access of cosimulation signals. Starting with release 6.2, Mentor has updated the default optimization flow which may result in cosimulation signals not being present or not having read/write access permissions needed by the Link for ModelSim product. If the signal does not exist or access is not available, messages similar to the following will appear in the vsim command console:
vpi_handle_by_name(): ERROR - Cannot find an object matching the name "mysignal" MLwarn - M-Function failure: Reference to non-existent field 'mysignal'
