19.3.1 MSVT.param File

(Ask a Question)

msvt.param is an auto-generated file that contains parameters required by MSVT to verify design separation. You can modify the contents of this file according to your requirements.

The following is a Top-Level view of an example design.

Table 19-1. Parameters in the msvt.param File
Parameter	Description
DEVICE	Name of the Microchip FPGA device implementing the design.
DESIGN	Location of the files required for MSVT. By default, it will point to the auto-generated msvt.dtf folder.
VERIFY BLOCKS	Contains a list of blocks to be verified. By default, all the block names present in the design are listed. You can modify this list and include a subset of blocks to be audited by MSVT.
REQUIRED_SEPARATION	Required separation parameter per the guideline requirements. The default value is 1.
MAX_VIOLATIONS_PER_REPORT_SECTION	Controls the number of violations that are to be reported in each section. The default value is 1.
IRS	Contains a list of IRS signal names present in the design. Each IRS statement is comprised of a pair of separated blocks followed by a list of the IRS signal names between them.
REGIONS_VERBOSITY	Controls reporting of each routing region and the assigned instances. The default value is 0.

You can modify the parameters in the msvt.param file to refine your verification criteria. We recommend modifying the REQUIRED_SEPARATION parameter according to your system requirements before executing MSVT. You can also specify the blocks you want to verify, the names of each IRS signal, and add a limit to the max number of violations to be reported.
