Follow asked Nov 9, 2016 at 11:26. It's highly likely that Quartus is incapable of dealing properly with objects of record types (while Xilinx Vivado has been making inroads in the last year or so). I am trying to do a circuit that get the MOD of two numbers, my problem is in the output of that circuit, the output shows 0 and then the correct value of MOD, i have to integrate this circuito to another circuit to do a circuito that shows if a number is prime or not. I'm writing individual VHDL modules then linking them together in the Quartus Prime schematic If you are using VHDL-2008 then you can use the sll operator to perform the shift, for example, to shift by one bit: shift_out <= input sll 1; Otherwise you can simply append a number of bits to the end of the input Quartus II Introduction Using VHDL Design This tutorial presents an introduction to the Quartus R II CAD system.

Led clignotante via le logiciel Quartus II MAX 10 ADC with VHDL / Quartus Prime Lite Code Optimisation. vhd in your Precision Synthesis project is optional, but you must add the file to your Intel® Quartus® Prime project along with the Precision Synthesis-generated EDIF or VQM netlist. Ask Question Asked 7 years, 9 months ago. In particular, VHDL simulators treat meta-values as real logic values rather than Don't Care values; for example, a comparison between a std_logic 1 and X results in FALSE. Now I'm doing a lab where we are constructing a blinking LED. 1 For some commands it is necessary to access two or more menus in sequence. Rozakos Rozakos.

Don't cross between std_logic_arith (package propios) and numeric Use the ieee. Use only numeric_std and you can do everything you need:. Over the past few days I've taught myself: How to write VHDL; How to make a component; How to write a testbench; How to use previously created and tested components - knitted together - to create a new component; Generate the PLL with the MegaWizard in Quartus Prime, and then include the generated . Then the operators are `sla`/`sra` for arithmetic shifts (ie fill with sign bit on right shifts and lsb on left shifts) and `sll`/`srl` for logical shifts (ie fill with '0's).
