WT dcache questions?

[sjthales]

Hello @Moschn and @zarubaf

I am working on the write through cache you designed.

I have some questions:

• I would like to reduce the number of way to 2 instead of 8 in default configuration today, I encounter a problem with lsfr.sv module which doesn't allow to have less than 4 for LfsrWidth parameter. According to you, is it possible to modify lsfr module in order it to be able to manage a LfsrWidth parameter equal to 2?
• I wonder if there is a link betwen ariane_pkg::DCACHE_SET_ASSOC value and DCACHE_INDEX_WIDTH which are both equals to 8 in default configuration or if these values are independants?

Regards,

Sébastien
