Problem Title:
Hardware Debugger: Readback verification disabled in XC5200 designs...
Problem Description:
Urgency: HOT
General Description:
Hardware Debugger states that the READBACK block is not present in the design; therefore, all readba
ck verification and debugging features are disabled. However, the Readback module was indeed used i
n the design.
MAP M1.4 has CR 104301 filed for failing to route the DATA pin of the READBACK symbol. Until a patc
h is available the only workaround is to manually edit the .ncd file in epic or return to the XACT6
S/W.
Solution 1:
To reroute the net connections in Epic Design Editor:
1. Invoke Epic on the routed ncd file. Specify Read/Write Mode.
2. Select the Net attached to the RIP pin of the RDBK comp to get the <net_name>.
3. Select the <net_name> in the Epic List.
4. Take note of all other connections to <net_name>. Click on other attached pins to get their <sit
e.pin> name.
5. Click on Delete. This will delete <net_name>.
6. Click on the .DATA pin of the RDBK comp as well as all other comp pins to be connected to this ne
t.
7. Click on Add.
8. Fill in the "Name:" field with the <net_name> of the net just deleted, and click on OK.
9. The net should now be routed. Save and exit.
