Post Implemtation Timing Simulation of XADC in Vivado 2014.4

Hello,

 

1. I am using XADC in Zynq device usign VHDL following attribute in generic;

 SIM_DEVICE => "ZYNQ",
 SIM_MONITOR_FILE => "D:\TTM\tb\design.txt"

 

behavioral simulation is running fine and its accepting analog input from design.txt file. As Vivado support verilog as target language for post synthesis and post implementation simulation so I set verilog as target language. in Simulator language I selected mixed as my testbench is in VHDL.

 

When I run post synthesis or post implementation simulations, the simulator is unable to find analog stimulus file. The log generates warning

 

WARNING: file D:TTM    bdesign.txt could not be opened
 *** Warning: The analog data file D:TTM    bdesign.txt for XADC instance ttm_system_tb.inst_ttm_system.inst_ttm_adc_module.ttm_adc_0.U0 was not found. Use the SIM_MONITOR_FILE parameter to specify the analog data file name or use the default name: design.txt.

 

2. Also I am verifying after implementation all the design internal registers and connections that its been routed perfectly, yes it is but when I start post implementation simulation then I get following warnings too which indicates that some objects are not present or simulator couldn't find them, in both cases my question is why ?

Any news on that?

I am running into the same issue and have no clue how to solve it...

 

Would appreciate any kind of help on this topic:)

Thanks,

BZI
