For example:
ERROR: Expected device not found at expected location.
Expected idcode:0011 0000000000000001 01100100000 1
Found idcode: 0000 0000000000000000 00000000000 0
PROGRAM ERROR: Exit code = 6... Unrecognized device
There are several potential solutions, depending upon the contents of the
Found idcode
.
•
If the found idcode is all 0s, the Bitporter did not find any device at the specified
location in the JTAG scan chain. Verify that the target deviceʹs power supply is
plugged in and turned on.
•
If the found idcode is all 1s, the Bitporter did not find a valid JTAG connection. Verify
that the JTAG cable is properly connected to the Bitporter and the target device.
•
If the found idcode matches the expected idcode except within the four leftmost bits,
then the Bitporter found an incorrect version of the specified Achronix Device at the
specified location. Verify the ACE Implementation Options

used to generate this
file, or call Achronix Technical Support for assistance.
•
If the found idcode matches the expected idcode in the twelve rightmost bits but not
the 20 leftmost bits (the two bit groups on the right match while some part of the two
bit groups on the left do not match), the returned ID code contains the correct
Achronix manufacturer code but incorrect device code. The Achronix device found by
the Bitporter at the specified location is not the required device. Verify the ACE Imple‐
mentation Options

assistance.
•
If the found idcode does not match the expected idcode in the twelve rightmost bits,
the Bitporter found a non‐Achronix device at the specified JTAG scan chain location.
Please verify the Bitporter is connected to the correct JTAG scan chain, verify the
location of the Achronix device in the scan chain, and/or correct the scan chain
location specified in the ACE Implementation Options
