Use slow asynchronous modul in a fast synchronous mealy state machine cause timing er

Hello everyone, 

 

how can i use a slow asynchronous modul to calculate signals in one state of a fast synchronous mealy state machine without the Error Timing requirements not met? I tried to use a clock enable signal slow enough for the asynchronous modul to finish but the error still remain. 

 

thanks and regards,

A clock enable signal doesn't change the requirements for timing closure. If the clock enable signal creates multi-cycle transfers, you have to specify them explicitely.
