The Sierra Exerciser is a traffic generator that emulates FC Initiator/Targets. Traffic generation enables engineers to test designs under realistic conditions and to transmit known errors, allowing engineers to observe how devices handle faulty link conditions.
Known limitations
Points to be Noted
-
Due to symbol rearrangement, in some cases there might be extra fill words inserted in the traffic.
-
When the exerciser is waiting to receive or doing some variable arithmetic operations, fill words are put on the line.
-
When no frames or primitives are transmitted, fill words are put on the line as per spec.
Limitations
-
Generation memory is limited to 16k memory blocks.
-
Back to back wait statements might miss the valid events if the gap between two successive event points is very small.
-
Loops, Jumps, If, else, while, when statements, and variable operations insert idles on the line during execution.
