• Loads bitmap onto the PIM’s FPGA.▪ Bitmap is a pin net list in VHDL code.
• Sends request to aircrafts LRU for its ID.
• LRU returns the value of the its specific ID.
• CAPRE displays the value.▪ LRU 155 ID = 020A.

Load/Verify
• Loads bitmap onto the PIM’s FPGA.▪ Bitmap is a pin net list.
• Loads a dummy file and sends dummy file to the LRU.▪ Dummy file is a simple text file.
• LRU returns a successful load if the dummy file was loaded correctly onto the LRU.
