The SPI-4.2 v9.1 Sink core might not lock to the data stream or go in frame during VCS simulation due to pulse swallowing.
To avoid this issue, the VCS switch "+transport_int_delays" should be added to the VCS command line as follows:
vcs +no_notifier \
+neg_tchk \
-debug -PP \
+transport_path_delays +pulse_e/0 +pulse_r/0 \
+transport_int_delays +pulse_int_e/0 +pulse_int_r/0 \
-sdf max:pl4_demo_testbench.pl4_wrapper0:../../implement/results/routed.sdf \
pl4_demo_testbench glbl
This command line switch will be added to the SPI-4.2 v9.2 core example design simulation script in the next release.
