### SEC_CM_IMPLEMENTED
Any appropriate security counter-measures are implemented.
+Implementations must follow the [OpenTitan Secure Hardware Design Guidelines]({{< relref "../security/implementation_guidelines/hardware" >}}).

-Note:
+In particular, note that:
- For duplicated counters [`prim_count`](https://github.com/lowRISC/opentitan/blob/master/hw/ip/prim/rtl/prim_count.sv) must be used.
- For duplicated LFSRs [`prim_double_lfsr`](https://github.com/lowRISC/opentitan/blob/master/hw/ip/prim/rtl/prim_double_lfsr.sv) must be used.
