2015-11-16harmonize ctrl and status addresses with other coresPaul Selkirk
2015-10-05Changed warmup cycles to a cool million.Joachim Strömbergson
2015-10-05(1) Added warmup functionality to the rosc entropy provider. (2) Changed ↵Joachim Strömbergson
name of enable port in the core. (3) Added a rudimentary makefile to allos building and linting of the rosc entropy core.
2015-04-28Remove the delayed read for EIM (see core/platform/novena commit 2f58e8f).Paul Selkirk
2015-04-13Added a simple parameterized zero extension to squash warnings in ISE and ↵Joachim Strömbergson
Verilator.
2015-04-13Adding a test design that instantiates a single Cryptech ring oscillator ↵Joachim Strömbergson
with registered inputs and outputs. This allow us to test implementations in different FPGA technologies for different oscillator configurations.
2015-03-26Adding a README for the rosc entropy source with a short description of what ↵Joachim Strömbergson
the core is, how it works and implementation status for different FPGAs.
2015-03-26Changed fromm hard coded oscillator adder width to localparam and updated ↵Joachim Strömbergson
operand sizes used. Changed to localparams for parameters since they don't need to be exposed outside the module. Updated the oscillator array instantiation to reflect what is done.
2015-03-25register data for eim outputPaul Selkirk
2014-11-14Added addresses and hard coded strings for name and version accessible from ↵Joachim Strömbergson
API. Updated API addresses.
2014-11-07Added Bernd Paysan as author.Joachim Strömbergson
2014-10-23Added Xilinx specific constraint attribute to preserve the ring oscillators. ↵Joachim Strömbergson
Fixed name of rosc instances.
2014-10-02Changed name of register to make it more obvious what it is.Joachim Strömbergson
2014-09-26Update of rosc entropy after synthesis of the trng.Joachim Strömbergson
2014-09-24Fixed synthesis warnings.Joachim Strömbergson
2014-09-24Adding an enable signal port for any consumers to know that the provider is ↵Joachim Strömbergson
active.
2014-09-24Updates to fix bugs found during synthesis. Adding more debug outputs in ↵Joachim Strömbergson
API. Adding security error port for future internal health tests.
2014-09-18Adding a new core for ring oscillator based entropy.Joachim Strömbergson
