2015-09-02Changed the max number of blocks to force reseed once every 256 TByte. ↵Joachim Strömbergson
Changed default number of blocks to do reseed once every 16 GByte.
2015-08-20Adding a stat counter for number of CSPRNG reseeds.Joachim Strömbergson
2015-07-18Fixed replication sizes found during lintint.Joachim Strömbergson
2015-07-18Simplified the pointer handling. Fixed size of counter. Now all positions in ↵Joachim Strömbergson
the fifo is used and flags are correctly set.
2015-05-22(1) Added a cipher block statistics counter. (2) Cleaned up the csprng code ↵Joachim Strömbergson
and connected discard for fast restart of trng. (3) Added addresses for allowing API to write a known seed to allow test mode. (3) Fixed a number of minor issues during linting. (4) Fixed the csprng testbench to actually generate data as well as displaying the block stat counter.
2015-04-28(1) Remove the delayed read for EIM (see core/platform/novena commit ↵Paul Selkirk
2f58e8f). (2) Add the code to read the csprng name and version registers.
2015-04-27Adding name and version fields to the csprng.Joachim Strömbergson
2015-04-27Updated the trng version number to sometning that better reflects that it ↵Joachim Strömbergson
actually builds and generates values.
2015-04-02(1) Added a state in the write fifo machine to actually drop request between ↵Joachim Strömbergson
csprng data words. (2) Updated the testbench with better test vector generation.
2015-04-01Cleanup and fixes of calculations.Joachim Strömbergson
2015-03-26Minor cleanup: Morged clocked processes. Changed name of api read data hold ↵Joachim Strömbergson
register. Changed to localparam. Removed redundant code for reg updates.
2015-03-26Minor cleanup: Changed to localparam for internal parameters. Merged reg ↵Joachim Strömbergson
update processes to one. Changed name of api read data hold reg and added better update vector name for it.
2015-03-26Changed to Verilog 2001 part select for word extraction.Joachim Strömbergson
2015-03-26More cleanup. Completed parameterization of fifo. Fixed incorrect size of ↵Joachim Strömbergson
control regs.
2015-03-26Cleanup from linting. Changing to parameterized fifo pointers. Fixed bug in ↵Joachim Strömbergson
bit selection.
2015-03-26Cleanup: Merged separate clocked processes. Fixed incorrect bit widths. ↵Joachim Strömbergson
Changed to localparams. Changed api data read reg to real hold register.
2015-03-25streamline(?) api_mux, register data for eim outputPaul Selkirk
2014-11-20Reworked the csprng output fifo to really take advantage of the fact that ↵Joachim Strömbergson
the csprng delivers blocks of 512 bits. Removed trailing whitespaces and linted code.
2014-11-20Updates after linting.Joachim Strömbergson
2014-11-20(1) Reducing timepout for entropy sources. Updated interface for sha-512 to ↵Joachim Strömbergson
match new interface with work factor ports. We are not using the work factor here at the moment.
2014-10-02Removing wrappers since they are not used.Joachim Strömbergson
2014-10-02Updating trng to debugged version.Joachim Strömbergson
2014-09-27Adding debug port for mixer and csprng. In the csprng the debug_update will ↵Joachim Strömbergson
trigger fifo extraction and thus force random number generation.
2014-09-26Updating source to the latest and greatest. In this version the entropy ↵Joachim Strömbergson
sources works and all modules have correct intterface.
2014-09-18Updates after synthesis of the complete trng.Joachim Strömbergson
2014-09-16Adding a minor readme to explain when to use the entropy wrappers.Joachim Strömbergson
2014-09-16Adding initial version of wrapper for the avalance entropy core to be used ↵Joachim Strömbergson
during synthesis.
2014-09-16Fixed incorrect bit index.Joachim Strömbergson
2014-09-16More debug fixes. We add one extra wait cycle to allow the mixer to detect ↵Joachim Strömbergson
that we want more seed.
2014-09-16Debug fixes found during simulation. Now the trng generates data and ↵Joachim Strömbergson
provides an api.
2014-09-12Adding first version of complete trng.Joachim Strömbergson
2014-09-11Update after completion of rtl and debug of rtl using the updated testbench. ↵Joachim Strömbergson
Now it works.
2014-09-11Adding initial versions of rtl and tb for the mixer.Joachim Strömbergson
2014-09-11Adding rtl and tb for the csprng part of the trng.Joachim Strömbergson
