tessent write_patterns时报warning，进行parallel仿真时报mismatch，求指点

yuming_ziyi

write_patterns时warning如下：

//  Warning: Scan chains contain shadow elements which can cause simulation
//   mismatches in parallel load test benches.
//   To correct for this, a second shift vector is being added when loading
//   the scan chains, this is similar to using a post shift in the
//   load_unload procedure.

parallel仿真时报01 mismatch
