Hi all,

Is there is any upper limit in the sensitivity list for a combinatorial always block..?

For eg :

If the combinatorial always block code is like :

always @ (posedge a or posedge b or negedge c...)
begin
end

My question is :
Is there like only 2 elements must be present inside the always block or can we write more..?

Thanks and regards
 

Code: 
always @ (posedge a or posedge b or negedge c...)
models edge sensitive sequential, not combinational logic.
 

a, b or c - Not clocks

So, I did not get how it models sequential logic..?
 

To model combinational logic, you'll write
Code: 
always @ (a or b or c...)
or
Code: 
always @ (a, b, c...)

There's no limitation on the number of events in the event expression.
