Vidado software version

[MohammadRezaRohanipoor]

Dear Jun Song Wang,

I am student and familiar with FPGA designing based on VHDL and Verilog languages. I did some simple FPGA projects by using Vivado software on Windows OS. I want to use AccDNN tool. So at first, I read README file and I install Ubuntu OS.

• On one hand, in part 3 of "Requirements" section, you mentioned "Install Xilinx Vidado software, and also add to environment, the hardware SDK was tested on Vivado 2017.4".

• On the other hand, in "Simulation without involing hardware" section, you mentioned "Only Vivado 2013.4 is supported in this simulation environment".

So, I am confused which version of Vivado should I install on Ubuntu?
Is it possible to install any version of Vivado for both simulation and implementation?
Since new versions of Vivado have large size and take more time to download, can I install old version of Vivado (such as versions 15.3 or 14.3)?

Regards,
Mohammad

Because simulation scheme after 2013.4 has big change in Vivida sepecially for its ipcore. At that time, we didn't find a good way to using modelsim to simulat the Vivado's generated IPcore, so we still choose the 2013.4 . For implementation, we don't have this requirements, I think 15.3 and 14.3 are both fine. Since we use some new FPGA chips for implementation, we choose 17.4 finnally.

Hello,
At first, I shall thank you for the answer.
I will install the Vivado and check the AccDNN tool as soon as possible.
