I have built the docker and cloned the snitch_cluster repo in /repo.
And then in the target/snitch_cluster, I use the command make bin/snitch_cluster.vlt

For which I get:
work-vlt/Vtestharness.h:11:10: fatal error: verilated_heavy.h: No such file or directory


What am I doing wrong here?


Commands I have used:
   

1. To build docker:
   
   Code:

   sudo docker build -t ghcr.io/pulp-platform/snitch_cluster:main -f util/container/Dockerfile .
   2.  In the snitch_cluster root: docker run -it -v $REPO_TOP:/repo -w /repo ghcr.io/pulp-platform/snitch_cluster:main
   3.  In /repo of docker: git clone https://github.com/pulp-platform/snitch_cluster.git --recurse-submodules
   4.  In /repo/snitch_cluster/target/snitch_cluster: make bin/snitch_cluster.vlt
   
   
   

When trying to run the setup for RTL simulation of the HERO Project's accelerator through synthesis, two modules are not synthesizable, namely axi_sim_mem and apb_stdout. Are there preexisting versions of these two modules that will pass synthesis, or would I just have to try and make them synthesizable while trying to maintain the default functionality as much as possible? TIA

Hi,
I tried to connect to pulpissimo via jtag using openocd, but always get this error:
   
I tried on 2 different fpgas: zedboard and zcu104 and get the same error. This is my openocd config file:
   
I have been struggle with this error for weeks and really need help :<

Hello everyone,

Im currently doing a research for a future proyect about RISC V based core IPs,  chips, devboards fully designed and manufactured in Europe that are being commercialized right now. Preferable if the devboard counts with multiple communication protocols, no FPGAs, less 25W consumption, no SoC.
If in development I  would also appreciate the information. I know SiFive is selling european designed and manufactured RISC V dev boards, but, the RISC V chips themselfs are manufactured in China.

Thank you in advance for the assistance.

Hi, I am Jay Huang, a Verification Engineer at Taiwan Electronic System Design Automation (TESDA). Currently, we are utilizing your open-source SOC, PULPino, to develop our verification tools.

During the course of our SOC implementation, we have encountered some challenges related to the PULPino Boot ROM, prompting us to seek clarification on certain aspects. According to the datasheet Memory Map, the Boot ROM's address range is specified as 0x0008_0000 to 0x0008_0200.

In an attempt to integrate this information into our testbench, I observed that when attempting to read from this address range, no data was retrieved. After further investigation, it was determined that the Boot ROM is, in fact, located immediately following the Instruction Memory, rather than at the specified address.

I would like to ask if it is correct to set the start address of the Boot ROM at 0x0000_8000 if the Instruction Memory is configured as 32KB?
If this configuration is indeed correct, I am curious as to why the Boot ROM's address in the datasheet is documented as 0x0008_0000 to 0x0008_0200.

Your insights and guidance on this matter would be immensely valuable to us in resolving the issues we are currently facing. Thank you for your time and attention to this inquiry.

Hi, 

I was trying to implement a solution to add AES and maybe other crypto extensions in Pulpissimo. I tried to change the core to a variant of the RI5CY, CV32E40S that support some of that extensions. 
When I run a test that worked on the original core, the JTAG halts the core in the simulation. 

I was wondering if there is something to do with the SDK (by the way, i'm using this platform for a while so i'm still using releases 7.0 and pulp-sdk) or the toolchain to make it work, or is it just a problem in the connection of the core. There are quite a few more ports so, just to start trying, I left some of the ports that seemed optional from the documentation. 

Thanks in advance.

Hello,

I am trying to generate pulpino's bitstream without using the processing system loading the programs via SPI SLAVE. I modified the pulpemu folder deleting all the processing system's part and I managed to generate the bitstream but I am getting this warnings:

Then with Vivado I transfer the bitstream to the zedboard and send the code to load the program via SPI SLAVE but I don't get any answer from MISO and it doesn't load the program.

Any help?

One question I have is whether I can deploy pulp with vivado for windows

tôi đang thực hiện SoC dự án Pulissimo trên FPGA. Tôi sử dụng Zedboard. Tôi đã gặp lỗi khi cố gắng sử dụng openocd để conig jtag để gỡ lỗi. Hãy làm theo hướng dẫn trong readme https://github.com/pulp-platform/pulpiss...nd-openocd
Tôi git sao chép và thực thi các lệnh sau xây dựng
bản sao openocd $git https://github.com/pulp-platform/riscv-openocd
$ ./bootstrap
$ ./config --enable-ftdi
$ ./make
$ ./make cài đặt

sau đó tôi sử dụng lệnh để kết nối riscv lõi với máy chủ
$ openocd -f openocd-zedboard-ftdi2232.cfg
Tôi nhận được mã lỗi sau:

Sau đó tôi chuyển sang một FPGA khác. cụ thể là kintex kc705. Tôi lại nhận được lỗi sau:

Cách định cấu hình bột giấy gỡ lỗi openocd khi được triển khai trên FPGA. Và tôi muốn triển khai Pulissimo xuống Kintex 7 KC705 FPGA. Tôi có thể làm được không? tôi đang gặp rắc rối

I am running a project with pulp-freertos and all the related tools needed to make it run (sdk and riscv toolchain). I am personalizing the 'blink' demo project already present in the github dir project, but I need to debug it. Now the question is...how can I debug it?
Thanks in advance
