I'm the lead developer of the TRNG and will gladly answer any questions you have. Let me give a short description first and then answer your current question. The Cryptech TRNG is a hybrid RNG with two separate entropy sources that feeds a digital chain implemented in the FPGA. The main entropy source is based on avalanche noise and is designed by Fredrik Thulin and Benedict Stockebrand. Schematics for this entropy source is available here: http://wiki.cryptech.is/browser/doc/design/Novena-entropy-board The second entropy source is implemented in the FPGA and is based on jitter between multiple free running digital oscillators. The source is designed by Bernd Paysan and me. This entropy source must be qualified for the given FPGA family you want to use and the layout should preferably be locked down to ensure similar behavior between separate builds. The source has been tested in both Altera and Xilinx devices. The source for it is available here: http://wiki.cryptech.is/browser/core/rng/rosc_entropy The PRNG part of the generator comprises of an entropy source mixer implemented using SHA-512 and a CSPRNG implemented using the stream cipher ChaCha. There are also some fifos etc. All cores needed to implement the TRNG are available here: http://wiki.cryptech.is/wiki/GitRepositories The top level for the TRNG is here: http://wiki.cryptech.is/browser/core/rng/trng As you can see from the source code, we use Verilog (2001-ish) as RTL language.
