connecting I/O pins together without inserting buffer

archive

Hi,

I have some I/O pins which are analogue and they must be connected together.(that's strange but this is what I have to do!!)
As in the verilog I use assignment stateent to connect these I/O pins together(assign output_pin_A = input_pin_B) , the RTL compiler insert buffer for them. I just wonder if there is anyway to connect them directly without inserting a buffer, (as they are analogue pins).
I guess that is something should be done during the routing stage, whether asking the nanroute to connect them using a feedthrough channel or something like this.

Thanks,

Houman
