Assertion "max_type" failed

[y8j31]

Hi,

VPR gives me the follow error when running with command "vpr customize_arch_11211025.xml ncl_blob_merge.blif" (all command set as default). And I am currently using the latest version which is update from github, any idea what could happen with the assertion failed?

If I change the code from "VTR_ASSERT(max_type);" to "VTR_ASSERT_DEBUG(max_type);", a segmentation falut will be occured.

Thanks for the report.

Can you provide the netlist and architecture files to reproduce the issue?

Hi @kmurray ,

Attached is the blif netlist and the architecture file. I am trying to place and route an asynchronous circuit with VPR. And the error shows up when I use the VPR command.
