core/util/keywrap - AES KEY WRAP as defined in RFC 3394

Age	Commit message (Collapse)	Author
2020-03-31	Merge branch 'integrate_mkmif' to master	Paul Selkirk

2019-01-17	Added non-zero default timeout value in core. This fixes the keywrap ↵	Joachim Strömbergson
	problems by not automatically reset the key in the API. Enabled all testcases and disabled excessive debug outputs.
2019-01-17	Debugging keywrap after auto_zeroise. Now the core starts processing as ↵	Joachim Strömbergson
	expected.
2019-01-17	Adding key timeout output port to allow core to inform the top level wrapper ↵	Joachim Strömbergson
	that timeout has occured. Added functionality to zeroise API key registers when timout has happened. Updated all auto_zeroise test cases to check that API key registers are properly zeroised.
2019-01-11	Add testcase that verifies forced zeroisation.	Joachim Strömbergson

2019-01-11	Adding test case that verifies that SW can keep a key alive by reading ↵	Joachim Strömbergson
	status register.
2018-12-20	Cleaned up and made auto zeroise test case 1 self-testing:	Joachim Strömbergson

2018-12-14	Splitted the auto-zeroise test case into three separate tests.	Joachim Strömbergson

2018-12-13	Fixed some bugs in auto-zeroise functionality. Now it really zeroises key ↵	Joachim Strömbergson
	automatically. It seems to work, but needs a bit more testing.
2018-12-11	Adding test case for auto_zeroise. Can see that a loaded key gets wiped ↵	Joachim Strömbergson
	after timeout. Status bits looks fishy though.
2018-12-09	Adding support for SW to keep loaded key alive by reading status. Adding ↵	Joachim Strömbergson
	support for SW to trigger zeroisation of a loaded key.
2018-12-07	Adding API support for key loaded status and key timeout control. Added ↵	Joachim Strömbergson
	ports in the core to support key status and timeout. Updated core testbench to match the new interface.
2018-12-07	Solved event loop.	Joachim Strömbergson

2018-11-27	Adding test that tries to write a key into the serial memory.	Joachim Strömbergson

2018-11-27	Adding check that correct status word was written into the serial memory.	Joachim Strömbergson

2018-11-23	Added ability observe mkmif state. Realized that the write operation handler ↵	Joachim Strömbergson
	was under read operation handling. Fixed this and now status write works. We can observe 0xdeadbeef in the memory after status write operation.
2018-11-23	Updated display of states. We can now observe correct init of the memory.	Joachim Strömbergson

2018-11-23	Adding task to dump parts of the contents of the serial memory.	Joachim Strömbergson

2018-11-23	Added observation of mem internal control states.	Joachim Strömbergson

2018-11-23	Enabled spi observation and can see that SPI interface is alive when pulling ↵	Joachim Strömbergson
	init.
2018-11-23	Adding test case for mem init. Removing auto-load test case since the dut ↵	Joachim Strömbergson
	does not support auto load. Updating the write status test case to use wait_ready() for dut status.
2018-11-22	Adding outputs to observe dut API. Adding support in Makefile for using the ↵	Joachim Strömbergson
	vendor supplied memory model.
2018-11-06	Fixed incorrect address used for the key. Added testcase to verify reading ↵	Joachim Strömbergson
	of status word.
2018-11-06	Adding test case to observe auto-load of key and status after reset.	Joachim Strömbergson

2018-10-30	Integrated the DUT into the testbench and update Makefile to build the sim ↵	Joachim Strömbergson
	target-
2018-09-28	Adding initial version of testbench for the mkmif wrapper.	Joachim Strömbergson

2018-09-28	Completed syntax debug after integration of new mkmif_core wrapper.	Joachim Strömbergson

2018-09-25	Added logic to perform status word read operation from the mkm. Adding ↵	Joachim Strömbergson
	interfaces and registers to be able to pass mkm status to host. Updated dut instantiation in core testbench to.
2018-09-18	Adding API control bits to read and write key.	Joachim Strömbergson

2018-09-18	Moved the mkmif instance into the core itself. Added API to read the key if ↵	Joachim Strömbergson
	DEBUG is set.
2018-09-14	Adding instatiation of the mkmif in the keywrap top level wrapper. Updated ↵	Joachim Strömbergson
	testbench anf Makefile to build with instantiated mkmif. The mkmif is not yet used by the keywrap.
2018-09-11	Adding a huge, self testing test case.	Joachim Strömbergson

2018-09-07	Updated testbench to use the new API. Verified that the new API works. No ↵	Joachim Strömbergson
	more banks.
2018-09-07	Removed r_bank from dump since it no longer exists.	Joachim Strömbergson

2018-09-07	Test write to all positions in the mem.	Joachim Strömbergson

2018-09-04	Updated rtl and tb to support parameterized memory size.	Joachim Strömbergson

2018-09-04	Updated testbench to handle parameterized core.	Joachim Strömbergson

2018-09-04	Updated testbench to work with the parameterized memory.	Joachim Strömbergson

2018-08-23	Adding top level defines for setting size and address bits.	Joachim Strömbergson

2018-08-16	Adding delay cycle to API regs to match the latency for accessing the ↵	Joachim Strömbergson
	blockRAM. Added test case that checks access to the API regs.
2018-08-15	Fix some misleading messages, and enable all tests.	Paul Selkirk

2018-07-06	(1) Updated version to reflect status. (2) Minor fix after running sim in ↵	Joachim Strömbergson
	ModelSim.
2018-07-06	Adding test case for 4096 bit unwrap. Testcase passed! We have unwrap.	Joachim Strömbergson

2018-07-06	Debugged key unwrap. First testcase for unwerap passed. Added some more ↵	Joachim Strömbergson
	debug outputs.
2018-07-06	(1) Fixed dump of core_addr in testbench to actually show the core_addr. ↵	Joachim Strömbergson
	Fixed boundaries for the block counter. Now we don't read mem out of bounds.
2018-07-05	Fixing block counter init bug. Enabling detailed debugging. Fixing minor nits.	Joachim Strömbergson

2018-07-05	Fixed minor details in unwrap test case. Enabled unwrap test case.	Joachim Strömbergson

2018-07-05	Adding unwrap test case.	Joachim Strömbergson

2018-07-05	Adding wrap test case with 4096 bit plaintext from NIST. Test result matches ↵	Joachim Strömbergson
	model.
2018-07-05	We haz keywrap! Time to add more testcases and make them self testing. Oh ↵	Joachim Strömbergson
	and implement unwrap.
