The current version of habanatools simulator changes could cause the issue. What you can do now is to use older 1.4.1-11 version of Habanatools (JFrog) and pull the 1.4 branch (git clone -b 1.4 GitHub - HabanaAI/Habana_Custom_Kernel: Provides the examples to write and build Habana custom kernels using the HabanaTools) , which is verified before.
In the meantime our new release 1.7 will be released very soon, and it will fix the current issue.
From 1.4 to 1.7, there is no change on kernel itself, only test_core simulator related change.
We just release the latest 1.7.0 habanatools, which fixed the issue you mentioned before. Now you can use this new release to build the codes from master or 1.7 branches.
