4.1i XC4000 PAR - Pad report does not contain TDI, TMS, TCK pins when a BSCAN symbol was instantiated


Keywords: pad report, TDI, TMS, TCK

Urgency: Standard

General Descriptions:
If a BSCAN symbol is instantiated, and TDI, TDO, TMS, and TCK are connected according to pages 6-45 of the 1999 Data Book, TDI, TMS and TCK do not appear in the pad report. This results in doubt regarding the enabling of the boundary scan circuitry.


You can verify the enabling of boundary scan circuitry by checking the PAR report file for the message:

BSCAN component "$I6" reserves 4 IOB sites): TCK, TMS, TDI, and TDO. These pins will also be included in the 'External IOB' count if they have user logic attached to them. Typically they do not, and are not included in the 'External IOB' count.
