Thank you for using AWS F1 instance. Regarding to the question on clock frequency, you're correct. Critical path will be different from design to design, or sometimes even from one build to the other. AWS provide several clocks that we think might be good fits for customer designs with different needs. Customer is required to choose from the clock group recipes (https://github.com/aws/aws-fpga/blob/master/hdk/docs/clock_recipes.csv) and cannot use arbitrary clock frequency. In addition, we have a dynamic clock configuration feature (https://github.com/aws/aws-fpga/blob/master/hdk/docs/dynamic_clock_config.md) in case you want an option to slow down design's clock frequency to meet timing.
For the GUI mode, we do have a NICE DCV support (https://github.com/aws/aws-fpga/blob/master/developer_resources/DCV.md). Please follow this page to set up the environment. Hope this helps!
Hi Chen ,
Thanks for the clarification. Sorry for the confusion. From GUI I meant VIVADO gui.
You should be able to run Vivado GUI using command
vivado once DCV is up and running. Please let me know if you see any problem.
I can open VIVADO gui from command but my query is as following.
Till now I have always running in non project mode. I just use provided scripts (makefile and all) to run simulation. My query is if I can run same project from VIVADO GUI so that once it completes I can see source file edit it there and run it again.
Right now I run everything in non project mode and then once test case finishes I just open waveform in vivado. To open a project into vivado I need project file. But I am not sure if any project file is created when I run in non project mode. If no project file is created in that case how I can run simulation in project mode?
Understood. It's feasible to create a local simulation project. That would require to manually add in all the per-compiled libraries and testbnech components to run RTL level simulation in project mode in GUI. Unfortunately, our whole verification environment is set up in the batch mode only in order to provide better compatibility with 3rd party simulators. We don't have a support for Vivado simulation running in project mode that you can directly leverage. I'll take the feedback to the development team to see if this is something we could support going forward.
