1.2.2.1. Clock and Reset Interfaces

Table 3.  Clock and Reset Interfaces
Signal Name Direction Description
in_clk Input This is the clock for the Avalon® streaming interfaces. The maximum frequency in 250 MHz.
in_reset Input This is an active high reset. Assert in_reset to reset the Mailbox Client with Avalon® Streaming Interface Intel® FPGA IP. When the in_reset signal asserts, the SDM must flush any pending activity from the Mailbox Client with Avalon® Streaming Interface Intel® FPGA IP. The SDM continues to process commands from other clients.
To ensure the Mailbox Client with Avalon® Streaming Interface Intel® FPGA IP functions correctly when the device enters user mode, your design must include the Reset Release Intel® FPGA IP to hold the reset until the FPGA fabric entered user mode. Intel recommends using a reset synchronizer when connecting the user reset or output of the Reset Release IP to the reset port of the Mailbox Client with Avalon® Streaming Interface Intel® FPGA IP. To implement the reset synchronizer, use the Reset Bridge Intel® FPGA IP available in the Platform Designer.
Note: For IP instantiation and connection guidelines in the Platform Designer, refer to the Required Communication and Host Components for the Remote System Update Design Example figure in the Agilex™ 7 Configuration User Guide.
