CTR_DRBG (SP 800-90A) using AES-256 (FIPS 197), configured without a derivation function; seedlen = 384 bits, 256-bit security strength, with reseed support. It is reseeded from the CMAC-conditioned entropy source and generates the module random output. Tested under ACVP as ctrDRBG. The algorithm is implemented for the Xilinx Artix UltraScale+ XCAU25P-2FFVB676I FPGA.
