Crash when using count value as vector signal

Below is my code
module simple_circuit(F,A):
input [0:3]A:
output [0:1]F;
assign F[0] = A[0] || A[1]&&A[2] || A[1]&&A[3];
endmodule

Then I used University Program VWF,
Insert the node, and choose A as count value signal, it crash.

Hi,

 

You can't use count value "count every" on bundled signals in vector waveform simulator. That only works on single bit signal. Check image:

Hi,


The function worked well in older version Quartus II. Tested in Quartus II 15 and 13. Quartus II 13 is still downloadable in FPGA Software Download Center. As vwf is generally older version simulator for Quartus II. For Quartus Prime, it's recommended to use modelsim/questasim simulator for more functionality.


Thanks,

Best Regards,

Sheng
