Once the SVF file is created, you can optionally execute the SVF file through Vivado IDE. Vivado IDE can execute SVF files generated through the SVF generation feature and is intended as the validation test tool. The
execute_hw_svf command is not intended as a general purpose SVF execution command; take care to only use SVF files created through Vivado IDE.
To run an
svf command you run the command on an open live target as follows:
execute_hw_svf my_file.svf INFO: [Labtoolstcl 44-548] Creating JTAG TCL script from SVF file INFO: [Labtoolstcl 44-549] Re-opening target in JTAG mode INFO: [Labtoolstcl 44-551] Sourcing JTAG TCL script: my_file.tcl Pass: SVF Execution completed with no errors INFO: [Labtoolstcl 44-550] Restoring target to original mode INFO: [Labtoolstcl 44-570] Execute SVF completed successfully
In this example, the file my_file.svf is executed. As part of the execution
flow, the input SVF file is converted via HW_JTAG Tcl operations into a temporary file.
After this Tcl code is created, the file is sourced to execute the converted SVF
instructions. To see the JTAG_TCL operations, you can run the
execute_hw_svf command using the
Once the command completes you will see either the error at the instruction where the
execution failed or a "Pass" message at the end of the message log.
