Michal Sieron f45ca410ad frontend/bist: properly signal finished writes 
Without it, software was resetting the generator too early and wrong
data was being written to the RAM.

Fix DFITimingsChecker for DDR4 simulation
 2022-11-18 12:47:13 +01:00
Michal Sieron f25604c153 Fix DFITimingsChecker for DDR4 simulation 
In case of DDR4 tRFC and tREFI timings are actually dictionaries with
timings specific for the chosen refresh mode.

Right now, it is impossible to simulate DDR4, because an exception
happens in `DFITimingsChecker.prepare_timings` method when indexing
`val` variable.

This is due to the fact, that in `DFITimingsChecker.__init__` we request
timing values from the module by name, ignoring the fact that some of
them (tRFC and tREFI) need to be first accessed using the chosen refresh
mode.

This commit fixes this error, by properly using `key` parameter when
calling `SDRAMModule.get` method to get only required timing.

If one were to fix it in `DFITimingsChecker.prepare_timings` method,
it would require duplicating logic from `SDRAMModule.get` so this is a
simpler and cleaner solution.
