wangweike

hi,thanks for you attention!

I use ELC in my work ,when i type the "db_prepare -force" there goes the warning:

elc>  db_prepare -force

then i type "db_date" ,it can not recognize the NOT gate

END_OF_DESIGN;

- feed-through ( A ) is found
- feed-through ( Y ) is found

can you help me to deal with it ?thanks very much

     Hello,

    Did you manage to solve this problem?

    I have the same case ()

    DESIGN INV should give

    INPUT A ( A );

    However it gives

     FEEDTHRU A ( A );

     

    As a result the gate is not recognized by the db_gate

    Thanks for your concern
