Hi everyone: I am new to FPGA and looking for a possible topic on FPGA routing algrithm. I read some classic articals in this field and find that when people are talking about routing algrithms (i.e. pathfinder) they generally ignore the architecture of switch box, while it is said that the topology of swich box may have an impact on the routability on the router. Thus, I am wondering how the router determine the path inside the switch box? And I am thinking is it possible to add the routing cost on the switch box to the cost function to the pathfinder algrithm?
I am totally new to the FPGA and its routing. I hope the above question may not be so naive. And I am still not sure which topic in this area is worthy to do. I appreciate if anyone give me some advice.
Thanks and happy new year.
