Problem Title:
PPR 5.2.x: XC5200 design with Readback gives ERROR 9905: NET "$I417/CLK" has no source
Problem Description:
Urgency: Standard
General Description:
*** PPR: ERROR 9905:
Net "$I417/CLK" has no source.
The router cannot continue until this functional error
is corrected.
Solution 1:
This error has been observed in an XC5202 design using the READBACK symbol. By default , when no s
ignal is connected to the CLK input, the internal CCLK is to be used.
If this error occurs, replace the READBACK symbol with the
RDBK symbol - which is comprised of TRIG, DATA, and RIP
pins - and no CLK input.
