Missing PAD direction for differential clock input in csv pin assignment logfile

Hi,

 

in the pin assignment log files (*.txt, *.pad and *.csv) generated from par the direction of the inverted

differential clock input is missing for V6. Please see the fillowing example:

 

Release 13.2 - par O.61xd (lin64)

 

*.txt

 

+----------------------------------------------------------------------------------------

|Pin Number|Signal Name  |Pin Usage|Pin Name      |Direction|IO Standard|IO Bank Number|

+----------------------------------------------------------------------------------------

|AH11      |gclk0_p_438  |IOB      |IO_L0P_GC_34  |INPUT    |LVDS_25    |34 

|AJ10      |gclk0_n_437  |IOB      |IO_L0N_GC_34  |         |LVDS_25    |34    

 

 

*.csv

AH11,gclk0_p_438,IOB,IO_L0P_GC_34,INPUT,LVDS_25,34,,,,NONE,,LOCATED,NO,DIFF_TERM,

AJ10,gclk0_n_437,IOB,IO_L0N_GC_34,,LVDS_25,34,,,,,,LOCATED,NO,DIFF_TERM,

 

*.pad

AH11|gclk0_p_438|IOB|IO_L0P_GC_34|INPUT|LVDS_25|34||||NONE||LOCATED|NO|DIFF_TERM|

AJ10|gclk0_n_437|IOB|IO_L0N_GC_34||LVDS_25|34||||||LOCATED|NO|DIFF_TERM|

 

Is this a bug ?

 

For differential clock outputs the direction is reported correctly for both pins.

 

Regards,

Sven.

Re: Missing PAD direction for differential clock input in csv pin assignment logfile

It doesn't seem to be a bug; it's just how the direction is shown in PAD report for diff clock. There is a related discussion on DIFF_TERM display.

 

 

Thanks,

Evgeni
