Microsemi BFM script language

• a very useful script language for bus performance estimation and bus functional check
• example:

• # read B uart 0;
  Reading offset 0 of uart – data = 0x1c
  # write B uart 4 bb;
  Writing 0xbb to offset 4 of uart
  # read B uart 8;
  Reading offset 8 of uart – data = 0x28
  # write B mac 30 11;
  Writing 0x11 to offset 30 of mac
  # readcheck B mac 11;
  Reading offset 0 of mac
  Error: Expected data = 0x11, Actual data = 0x22
  Test Failed, with 1 error

• advantage
• simple 
• error check 
• disadvantage
• no time stamp
• maybe it use ASAP(as soon as possible) methodology to transfer transactions, it means masters or slaves are not in busy status, or fetch/push buffers not full
• no atomic transfer
• if valid/ready is not continuous in the burst transaction, the interlevel transactions will happened, 
• like A1(4), A2(4), A1 has burst 4 trxs, A2 has burst 4 trxs.
• A1(2), A2(2), A1(2), A2(2) => atomic transactions when the A1 or A2 has busy or error in the internal transaction.
