*One instance of: “<span style="color:#55E439">ERROR:NgdBuild:989 - Failed to process BMM information edkBmmFile.bmm</span>”
*Followed by many instances of: “<span style="color:#55E439">NgdBuild:604 - logical block '[block_name]' with type '[block_name]_wrapper' could not be resolved. A pin name misspelling can cause this, a missing edif or ngc file, case mismatch between the block name and the edif or ngc file name, or the misspelling of a type name.
