Parameter Name

Parameter Description

Interface Name

Enable HPS-to-FPGA cold reset output

Enable interface for HPS-to-FPGA cold reset output

h2f_cold_reset

Enable HPS warm reset handshake signals

Enable an additional pair of reset handshake signals allowing soft logic to notify the HPS when it is safe to initiate a warm reset in the FPGA fabric.

h2f_warm_reset_handshake

Enable FPGA-to-HPS debug reset request

Enable interface for FPGA-to-HPS debug reset request

f2h_debug_reset_req

Enable FPGA-to-HPS warm reset request

Enable interface for FPGA-to-HPS warm reset request

f2h_warm_reset_req

Enable FPGA-to-HPS cold reset request

Enable interface for FPGA-to-HPS cold reset request

f2h_cold_reset_req

Figure 157. Recommended SDRAM Reset Connections

The SDRAM reset relies on the f2h_cold_reset_reqto be enabled. The reset can be enabled through the Platform Designer (Standard) Resets tab.

Note: SDRAM and the EMIF conduit can be enabled through the Platform Designer (Standard) FPGA Interface and SDRAM tab.
