Hello All, What kind of support have Altera for testing custom user component with AXI4-Lite interface? There is AXI BFM? Thanks

--- Quote Start --- There is AXI BFM? --- Quote End --- Yes, but it costs extra. The license is for the Mentor Graphics AXI BFM. Xilinx has a similar policy, but their third party BFM is from Cadence. I'm not sure why both Altera and Xilinx have decided to use AXI, and then not provided their customers with a free BFM for verification. I have not really looked into using AXI because of this issue. It would be nice to see an open-source AXI BFM. If anyone knows of one, please post to the list. Cheers, Dave

I am using AXI for my components because I can interconnect it to NIOS throught adapter, ARM natively and Microblaze on Xilinx stuff :) I have a design that should run on Altera AND Xilinx devices. Yeah, would be nice to see a free/open AXI BFM

I have not tried it ... please post your impression if you look at it http://syswip.com/axi4-lite-verification-ip Cheers, Dave

I had an awful time integrating AXI in with the HPS. What I found: 1) No TID conversion, so your module should store the TID with each transaction to push it back out to BID. This is because the AXI module TID needs to match the HPS TID 2) I wasn't able to get the address space to convert correctly when using an AXI component. Instead of translating the address, Qsys was just passing through the lower address lines. If someone has used AXI with Qsys and the HPS, I'd love to know, as I really had no luck after spending a week+ debugging Qsys issues with the interconnect. I was seeing that while Qsys DOES support AXI, there seem to be several undocumented limitations. EDIT: Not to mention that there is an AXI Timeout bridge that should be used, but there is no Linux kernel module for it or integration with memory writes/reads.

Hello tricky,

I have invested a lot of time porting my designs to AXI. I am very sorry to hear this.
I always have used some self-written procedures to test my AXI components.
I have visited link but i haven't found "axi verification components", where do you have downloaded it?

Thanks

You are completely correct-- it looks like everything has moved around on the site again. I know that it was necessary to have an ARM Silver account to download them, but there were verification components available for APB, AXI3, AXI4, AX4Stream. If I run in to them again I'll post a link here, unless Tricky has seen them recently.

That's definitely them. They've removed a couple of them (APB, AHB). Thanks Tricky!

This post is now 6 years old. Just out of curiosity, does Intel actually plan to obsolete the ARM based SoCs? I do not understand what else they could use when Microsemi and Xilinx also use ARM. If ARM is present, AMBA buses will be required as well. Also, as far as I am aware, the AXI BFM is present in Quartus Prime by default.

This old post has confused me.

  I doubt it (at least any time soon) since even the newest Agilex devices have SoC variants. And yes, the AXI BFMs are included in Quartus.
