Pass transistor logic and multi-valued logic in a FPGA

[Nitin]

Hi everyone,

Thanks a lot for showing interest in what I am doing. And I am
really sorry for replying so late. Actually we are trying to implement
a bypass bi-directional MOSFET transistor in a FPGA for bus purposes,
which does not need a signal that controls the direction of signal
flow, and acts like a switch. The transistor connects it's 2 terminals
(Source and Drain) when enabled and allows signal flow in either
direction depending on the strong value on a terminal. And tri-states
it when disabled. Do you have any information in this regard.
Actually as a part of my on-going research, I am faced with a new
problem of implementing multi-valued logic in a FPGA which actually is
an intricate part of the above issue of implementation of a MOSFET in
a FPGA. Does anyone have information in this regard? Any types of
comments or information is welcome. Does Xilinx provide such a
facility?

I am really thankful to Mr Rick, Mr. Mike and Mr. Jim for showing
interest in this topic

Thanks for all the help. I am looking forward for more mails on this
issue.

Thanks

Nitin

This sounds like IDT's quickswitch functionality.

Have a look at...
