Hi,
I'm trying to preload the program in L2 cache but i'm unable to trace which addresses goes into which memory
so far what i got tracing is the hello world example:
/tb_pulp/i_dut/soc_domain_i/pulp_soc_i/l2_ram_i/bank_sram24k_scm8k_pri0_i/cut_0/MEM
addresses in stimuli file from 1C000000 - 1C001030 go in this memory
/tb_pulp/i_dut/soc_domain_i/pulp_soc_i/l2_ram_i/bank_sram_pri1_i/MEM
address in stimuli file from 1C008000 - 1C00AF80 go in this memory
but i have no idea where the rest goes.
Question 1: is the mapping mentioned anywhere in the hdl files?
Question 2: I've not been able to build the documents in ipstools due to python libraries errors is there a pdf or a latex version i can get anywhere else online?
Thanks,
Bassma

Dear PULP user / PULP team member,
For a while now, PULP has been gaining momentum and as a result, we decided to start a forum. This has been done with the intention to increase the visibility of PULP's support. Since the support has been currently provided via pulp-info and dedicated GitHub pages, it is not easily searchable. Another reason why we decided to start a forum is the intention to build a community around PULP and possibly promote frequently engaged users to moderators. Based on the number of support requests received via pulp-info we decided not to create dedicated subforums, but we do not exclude that this might happen in the future.
