Version 0 of Xilinx demo board pin names extractor

Theo Verelst

It might not be something all tclers are into, but it is certainly in direct line of the origin of the tool command language and its graphical extension Tk.

Everybody who owns the Xilinx [L1 ] / Diligent CoolrunnerII demo board (which is fairly cheap if you're into digital hardware) will know the pin mapping problem: the digital circuit design program allows names for external pins, and the pin assignment tool lets you map those names to one of the 144 pins of the coolrunner Complex Programmable Logic Device chip, and then you need the Diligent [L2 ] datasheet of the demo Printed Circuit Board to figure out how all these pins are connected to 3 40 pin interface connectors, to connect you wires to.

Completely doable job, but with 120 pins, things get tedious late at night, so there is a perfect job for tcl and tk (and I used BWise, but that's not really necessary here, I just used the main canvas). I started by clipping the conversion table from the board datasheet (PDF) file, and pasted it into the bwise text window (opened by using 'open_text' in the console), which is widget .tt.t :
