Device, Package, and Speed Grade Selections
AMD Versalâ„¢ design families are supported.
Clock Frequencies
The CDBCAM has three independent clocks:
-
key_clk
- Used for the core logic and the interface to the NoC. The frequency is set using the parameter LOOKUP_FREQUENCY_INTERFACE and can range between 15 MHz and 400 MHz.
-
s_axi_aclk
- For reading and writing key/response pairs to the CDBCAM over an AXI4-Lite interface. Up to 150 MHz.
-
mem_clk
- Used for interface to the NoC. Up to 250 MHz.
Clock Management
The frequency for key_clk
is configured
using the LOOKUP_FREQUENCY_INTERFACE parameter in the Vivado IDE.
In dual clock mode, the frequency for mem_clk
is configured using the
MEMORY_FREQUENCY_INTERFACE parameter in the Vivado IDE.
The example design has generated clock constraints for
key_clk
, mem_clk
(DUAL_CLOCK) and
s_axi_aclk
.
Clock Placement

Banking
For DDR IOBs, placement is dependent on the Versal device part number used. Refer to Configuring Memory IP in the Vivado Design Suite User Guide: I/O and Clock Planning (UG899).
