RE: [sv-bc] enum value uniqueness

If you are asking if it's OK to re-use the symbol IDLE, even though it
may have the same value, the answer is: No.

 

Remember that simple assignments to enums are supposed to be type-safe,
and each label of an enum is visible in the current scope.

Subject: [sv-bc] enum value uniqueness

 

Hi, 

Should the following be legal? 

enum_logic [1:0] {IDLE ='0,START_XFER,WAIT_DONE} xfer_state; 
enum_logic [1:0] {IDLE ='0,START_REQ ,WAIT_ACK } req_ack_state; 

What about this? 

enum_logic [1:0] {IDLE ='0,START_XFER,WAIT_DONE} xfer_state; 
enum_logic [1:0] {IDLE      ,START_REQ, WAIT_ACK } req_ack_state; 

Thanks, 
Shalom
