解决方案

This signal might assert if you have streaming enabled, but then throttle the packet by deasserting trn_tsrc_rdy_n. When streaming is enabled by asserting trn_tstr_n, you must provide the packet without throttling during middle of the packet (from trn_tsof_n to trn_teof_n). If you throttle the packet when trn_tstr_n is enabled, this signal asserts indicating there is an error.
