- Vivado synthesis fail. conditional expression could not be resolved to . . .
Vivado synthesis fail conditional expression could not be resolved to a constant
- [SOLVED] - Vivado Synthesis failed with No errors or warnning
I've seen Vivado and ISE before have issues with valid code that just doesn't synthesize correctly or throws errors unless you change avoid some specify coding style Maybe the QA testing runs the tools on files with port mapping using the "=>", so it's hit or miss with positional mapping
- [SOLVED] - How to fix intra clock timing violation
Some times by trying few strategies in Vivado, the tool solves the timing violations, but what if it doesn't ? Question 1 : Can I always set false path for violation occurring at inter-clock-path ? ( provided , CDC is taken care in RTL ) Question 2 : How to solve Intra-clock-path timing violations ( setup and hold ) Thanks in advance
- Simulation does not start in Modelsim when using Xilinx IP-cores.
In my work I used to: (1) Once only in Vivado => tools => compile simulation libraries, choose modelsim and the target folder (2) Add to file "modelsim ini" the following mapping: unisim = C: … above location 3) In modelsim compile manually or write tcl to compile your code and the ip sim_netlist Check if you have a local modelsim ini as it will overwrite the main ini located in modelsim
- Vivado in combination with vitis question - Forum for Electronics
I think the OP should create a new thread and articulate the question and project requirements clearly This thread on use of Vivado or Vitis has been answered in my opinion
- [SOLVED] - Post-Implementation Timing simulation for Ring oscillator
So to conclude, for post synthesis and implementation timing simulations using Vivado 2014 1, one should use the Verilog Design sources and testbench The design sources can be in VHDL but for that the target language option in project settings should be selected as Verilog
- How to determine your critical path from Xilinx Timing Report?
Dear All, I have a design which uses a DCM to downscale my main clock to 5 more clocks When I see the PAR timing report It shows, different paths, how can I figure out that which path is actually is the critical path? It also shows that: Clock to Setup on destination clock clk_in
