Hello,
Into our design we have configure NOEL-V processor with XLEN = 64 (configuration CFG_NOELV_XLEN = 64)
We would like to have the internal AHB size to 32 bits length (configuration of CFG_AHBDW=64)
In this configuration the ISA test suite and 64bits instructions in general are not working. This is normal ? We haven’t found into the library documentation a clear sentence about that.
Thank you for your reply.
Regards,
Lucas
Hi Lucas,
I am not sure if I follow. The AHB size is set to 64 bits according to the constants, but you mentioned 32. Which one is correct? Relevant text below:
“We would like to have the internal AHB size to 32 bits length (configuration of CFG_AHBDW=64)”

Hello,
You are right i have made a mistake.
My configuration is AHB 32 bits => CFG_AHBDW=32
My CPU XLEN is set to 64 with CFG_NOELV_XLEN = 64
For this configuration it doesn’t work. Is it normal ? Do we have to make some others configuration ?
Thank you for your reply.
Best Regards,
Lucas
