Hi adunsmoor,
I am new to OCv and AOCV concept. From the articles which you pointed, I came to know that OCV is optimistic for shorter paths. How can OCV be optimistic for shorter paths?
As per my understanding in OCV a common derate value is applied to all the clock and data paths. Since we are...
Hi All,
I am doing DFT insertion for the first time. Now I am stuck fix a violation " Reset being used as D input to a DFF".
I tried to fix it using autofix option by enabling -fix_data enable.
But during preview_dft it is saying that no violation needs to be autofixed.
Can anyone help me to...
hi all....
i am interfacing an lcd with fpga. i want to convert the character to ascii so that i can display it using an lcd. i am storing the characters to be displayed in a string and using for loop i am retrieving it one by one. but i need to convert it to ascii. i am using vhdl. is there any...
hi....
the problem is solved. it was a problem with my code. i replaced the loop statements with if construct. then it worked. the problem was whenever positive clock edge comes the program terminates. also i learned that you can change the time for which waveform is displayed by right clicking...
i ran behavioral simulation by selecting the test bench. mask is declared as inout as i am reading as well as writing value to it. first i assigned value to mask within the second process but error was displayed when i synthesized it saying "its a bad assignment". thatsy i wrote its value in...
hi sir,
it was the problem with my code. was not entering the loop. So i modified the code but it doesnt produced any delay. i think the problem is that the signal mask is always having a value 'U'. can you pls help me in finding the error. i tried alot but it was not fruitful. the code which i...
hi....
for simulating my project i created a test bench using ise 14.3 .. but when the behavioral model is run only waveforms upto 500ps are displayed. the clk period is 1ns. how can i increase the time for which waveform is displayed?
Dear barry,
in the first case i set up a counter , ie; i incremented it frm 0 to 1000000 and outside the loop i am reseting the variable to 0 so that it will do the same when it enters the loop next time. That is what I meant while writing the code. Incrementing a counter as well as decrementing...
as it is not possible to produce synthesizable delay using "wait for " statement i wrote the following code. But it shows some error , I did'nt understand what the error was. i wrote the following code within the process statement.
process(clk)
variable count:integer;
begin

hi.....
I am also new to the world of FPGA... I need to interface an lcd module with fpga. My doubt is that whether i need to provide the ASCII value of each character to be printed separately or can i define an array of the characters to be printed and given to the data bus of LCD one by one...
Thanks for replying.......
so if I do some mathematical manipulations for eg if i multiplied the timer's value by 5 (tmro*5,after disabling the clk to counter) and i compared the result with its hex equivalent, wil i get the same result as if i compared with the decimal equivalent???? as per...
