sir ur videos r understanding vry clearly amazing

[@mben708]

Thank you. That was really helpful

19:48 - 1/50M is not 50micro sec

[@EDUVANCE]

It should be 0.02 micro seconds. Apologies for the inconvenience.

[@akshayudupa6105]

Your videos are very understandable. Thank you!

hi Dr. Jonathan Joshi, can we use any flipflop direct from library in vhdl while we designing mod-3 counters... like we pic up filpflops as component in schematic design...

[@EDUVANCE]

Yes you can do that. Following is the link to the guide for Flip - Flop component selection : www.xilinx.com/support/documentation/sw_manuals/help/iseguide/mergedProjects/destech/html/cs_flip_flops_component_selection_guide.htm Taking example of Asynchronous D- Flip flop. To directly use D - flip flop you can refer the following link which shows the input and output port names to be used. www1.pldworld.com/@xilinx/html/technote/tool/manual/15i_doc/alliance/lib/lib5_9.htm So now while you are creating the instances you will declare them with same names. Example: XLXI_20 : FDC port map (C=>CLK, CLR=>CLR, D=>XLXN_44, Q=>A_DUMMY);

Thanks alot Dr. Joshi

Sir,how to use for loop in vhdl ?? Will you please explain with an example

[@EDUVANCE]

The code below is an example of how to use for loop in VHDL. In this code, If the input is 1, then it is inverted or else the output is same as input library IEEE; use IEEE.STD_LOGIC_1164.ALL; entity MainModule is Port ( invert : in std_logic; input : in STD_LOGIC_VECTOR (3 downto 0); output : out STD_LOGIC_VECTOR (3 downto 0)); end MainModule; architecture Behavioral of MainModule is begin process(invert,input) begin if (invert='1') then for I in 0 to 3 loop output(I)

I am taking this class at TUM Munich and 3 weeks in what we are doing is more advanced than this vid, not bragging, but I am really struggling in my class.
