- __ M2.04__ SDRAM test suite
In support of HT3 tests conducted by Hardware Developer, write
gateware module to test SDRAM power consumption and signal integrity.
The test shall be developed in coordination with Hardware Developer and with
their HT3 test workflow in mind.
- maximum I/O bandwidth (64Gbps), refresh disabled
- continuous precharge/activate cycles in one bank at the maximum rate
permitted by the chip and the available command bandwidth
- continuous data transfers on other banks with the following pattern
- 0x5555... / 0xaaaa... to test for cross talk
- 0xffff... / 0x0000... to test for ground bounce
- one row in the data test bank permanently open
Adapt to be included in ARTIQ built-in self-test suite.
