Assertion '1 == driver_switches.size()

[kpatinos-intel]

Hello! I am using the latest version in master branch, and I am defining a new architecture. Now I am facing an Assertion Error I don't know how to tackle. It is hard to check what I am doing wrong in the arch definition or if it is a problem in the framework (less likely).

Backannotated 25 General Switch Blocks (GSBs).

Build General Switch Block(GSB) annotation on top of routing resource graph took 0.00 seconds (max_rss 60.5 MiB, delta_rss +0.0 MiB)

Sort incoming edges for each routing track output node of General Switch Block(GSB)

Start sorting edges for GSBs up to [5][5]
[4%] Sorted incoming edges for each routing track output node of GSB[0][0]
[8%] Sorted incoming edges for each routing track output node of GSB[0][1]
[12%] Sorted incoming edges for each routing track output node of GSB[0][2]
[16%] Sorted incoming edges for each routing track output node of GSB[0][3]
[20%] Sorted incoming edges for each routing track output node of GSB[0][4]
[24%] Sorted incoming edges for each routing track output node of GSB[1][0]
[28%] Sorted incoming edges for each routing track output node of GSB[1][1]
[32%] Sorted incoming edges for each routing track output node of GSB[1][2]

So if you could provide any insight what could be wrong or how to solve this issue I will apreciatte.

Thanks Kevin

@kpatinos-intel It could be some routing tracks or inputs of your programmable blocks have no drivers. Or you defined different types of switches that drive a routing track or inputs of your programmable blocks
