4.5. Dynamically Disabling the SM4 Capability
In addition to the Quartus® Prime parameter editor option, follow these steps to dynamically disable and re-enable the Symmetric Cryptographic Accelerator Hard IP's SM4 capability through the control register access:
- To dynamically disable the SM4 capability:
- Set the sm4_disable signal: 0x00[2] = 1'b1
- Set the cif_latency_pipe bits to 0x34: 0x08[23:16] = 0x34
- To dynamically re-enable the SM4 capability:
- Clear the sm4_disable signal: 0x00[2] = 1'b0
- Set the cif_latency_pipe bits to 0x3C: 0x08[23:16] = 0x3C
