FIR Compiler v7.2 系数reload后s_axis_reload_tready何时会拉高？

[tianzhi4981]

FIR Compiler v7.2 的IP Product Guide 中关于s_axis_reload_tready信号的解释是：tready for RELOAD channel. Asserted by core to indicate core is ready to accept data.当所有系数重载结束后，s_axis_reload_tready会拉低，但多长时间会拉高？与哪些信号有关系？通过ila调试核发现，重载结束后，s_axis_reload_tready维持低电平的时间从500us到100ms不等，FIR的时钟周期是17.8ns。

It's determined by Reload Slots setting, if the reload slot is full, the s_axis_reload_tready is de-asserted, if a configuration packet is sent to the core and and reload slot is released, then s_axis_reload_tready is asserted. You can run behavioral simulation to check it.
