Creating Orcad symbol for FPGA with large pin counts

I am using Orcad version 9.2 to create orcad symbols. I am trying to
follow a method described earlier in the same newsgroup. I am
describing pointwise the steps am following:

1) I downloaded the pinout table from Xilnx website
2) I sort the pinout in excel based on bank number
3) I create a new part in a library in Orcad and place the number of
pins I need using "place pin array" command
4) I select the pins whose name and pin number have to be changed and
press "CTRL + E" and I get the browse spreadsheet editor in Orcad.

After that I am not able to do anything other than copy the contents
of the Browse spreadsheet editor. To insert the pin names I select the
coloumn "Name" and I press ctrl + insert, but nothing happens
For instance after I select the "Name" coloumn to be replaced by the
contents I am trying to paste, the commands like "paste" , "copy"
among others just goes unusable(the letters on those commands goes
grey from black). Actually the paste is not active at all irrespective
of whether I select any coloumn or not.

Is this a version problem? I see Rotem Gazit had posted this message
in 2001.
Please let me know if you have experienced this difficulty before.

Krishna,

You have to organize the Xilinx spreadsheet such that the pin-name and
pin-number are in the same colunm order as what's in the Orcad spreadsheet
(what you see when you select the placed pins and do "properties".

Once you've done that, go to the Xilinx spreadsheet and select BOTH columns
of cells (name and number). I select the data and don't select the whole
columns (I'm not sure if this really matters). Once selected, do a CTRL C.

Now, go the Orcad spreadsheet. Select the cells of both columns (name and
number) and do a SHIFT INSERT. Close the Orcad spreadsheet and you'll see
the name and number's inserted into your symbol.

Good luck,
Bob
