CRC jam file

Hi,

Using the jam file below

-------------------------------

NOTE MAX_FREQ "10000000";

ACTION CONFIG_IO = EXECUTE;

PROCEDURE EXECUTE;

BOOLEAN X = 0;

DRSTOP IDLE;

IRSTOP IDLE;

STATE IDLE;

IRSCAN 10, $015;

DRSCAN 32, $FFFFFFFF;

STATE IDLE;

EXIT 0;

ENDPROC;

-----------------------------

I simulated the above jam file using quartus_jli.exe (command line jam player), it gave me output as

----------------------------------------------------

Expected CRC not found, actual CRC value = AB60

Export: key = "JAM_STATEMENT_BUFFER_SIZE", value = 1051

NOTE "MAX_FREQ" = "10000000"

Exit code = 0.. Success

-----------------------------------------------------

Using the above JAM file, I modified the line# 9 to an arbitrary number ("1FFFFFFF1"), to change the CRC checksum value and i got the output as

-----------------------------------------------------

Expected CRC not found, actual CRC value = 493F

Export: key = "JAM_STATEMENT_BUFFER_SIZE", value = 1051

NOTE "MAX_FREQ" = "10000000"

Exit code = 0.. Success

----------------------------------------------------

In this simulation, I am not able to understand the "Expected CRC not found" instruction.

Can anyone please help me about this problem and suggest me the solution.

Thankyou in advance
