1.4.5.9. SIP Partial Bitstream Generation

The Programmer generates a bitstream file containing only the bits for a safety IP. This partial preserved bitstream (.ppb) file is for the safety IP region mask. The command lines to generate the partial bitstream file are the following:
  • quartus_cpf --genppb safe1.psm design.sof safe1.rbf.ppb
  • quartus_cpf -c safe1.psm safe1.rbf.ppb

The .ppb file is generated in two steps.

  1. Generation of partial SOF.
  2. Generation of .ppb file using the partial SOF.

The .psm file, .ppb file, and MD5 hash signature (.md5.sign) file created during partial bitstream generation should be archived for use in future design modification flow compiles.
