2.2.2. Warm Reset Sequence Triggered by Hot Reset

  1. HIP asserts pld_link_reset_req to the GTS AXI Streaming IP.
  2. The GTS AXI Streaming IP notifies the user reset controller by asserting p<n>_initiate_warmrst_req.
  3. The user reset controller then asserts p<n>_subsystem_rst_req.
  4. The GTS AXI Streaming IP sequences its internal blocks for reset entry. When the internal blocks are ready for reset, the GTS AXI Streaming IP asserts p<n>_subsystem_rst_rdy to the user reset controller.
  5. The user reset controller acknowledges to the subsystem that it is ready for reset by asserting p<n>_initiate_rst_req_rdy.
  6. The GTS AXI Streaming IP then asserts pld_warm_rst_rdy to HIP.
  7. HIP asserts p<n>_reset_status_n indicating the application logic needs to be in reset.
  8. The user reset controller asserts p<n>_subsystem_warm_rst_n, p<n>_axi_st_areset_n, and p<n>_axi_lite_areset_n.
