Routing Switch Box

Hi,

Is there any information from Xilinx about internal structue of routing switch boxes, on any FPGA generation? During manual routing I found out that by clicking on a switch-box pin, all possible routings are shown, but I am curious to see if there is any document about it.

Hi @hamze,

 

For manual placement and routing please go through the following links:

for ISE:

Thanks Arpan,

Actually I know how to do manual routing, I am just curious about structure of switch box, I already know there are few different popular architectures ( wilton, disjoint,...)...

is there any published information about this from xilinx?

@hamze , Did you get any reference to know internal structure of Xilinx FPGA switchboxes?

it was long time ago, but what I remember was they are commercial secrets. However, by manual routing, you may get some information about possible connections.
