Missing modules during synthesis in CMAC #159

Closed Y159753 closed 6 years ago

Y159753 commented 6 years ago

Design compiler succeed to synthesize 4/5 partitions, however in partition_m there are two modules missing.

here is the final error message from design compiler :

I suspect you're not licensed for these designware building blocks. You may need to compile with DW disabled (set USE_DESIGNWARE to 0 in the tree.make file).

If you are licensed for DesignWare libraries, then you should check the LINK_LIB variable in your configuration. Please make sure it includes the DesignWare synthetic library.

If you have a standard Design Compiler install, these paths can be added to LINK_LIB

    ${DC_PATH}/../libraries/syn/dw_foundation.sldb
    ${DC_PATH}/../libraries/syn/gtech.db
    ${DC_PATH}/../libraries/syn/standard.sldb

My problem is solved, thank you. I added the 3 path you gaved in the LINK_LIB. But I also had to include in the TARGET_LIB : ${DC_PATH}/../libraries/syn/dw_foundation.sldb ${DC_PATH}/../libraries/syn/standard.sldb

Closing issue.
