    Difference between Logic and Reg in System verilog

    Hello , Logic and Reg in System verilog are 4 state variables and are of user defined size . What is the difference between them .If none what is the use of having two data types?

    Clock Frequency Division with varying frequency

    I have a main clock . I should divide the clock according to the number present in a 32 bit register which keeps on varying at regular intervals . Can some one suggest me how this can be done ?? The duty cycle of the new clock should be 50 % or anywhere close. I tried in the following manner ...

    Verilog efficient coding

    I was going through some verilog stuff , I came across this . I dont have a clue ,Can anyone help me what the author is trying to say Just as it is important to write code at a level of abstraction where vectors are the primary data type, it is also important to write code which does not...

    Pipelining to make the circuit work faster

    Thank you guys for your help , I am still very new to programming I had not run the program before , I just had done it theoretically integer ix; always @(*) begin res=0; rv=0; diff=Diff; for(ix=0; ix < 24; ix=ix+1) begin rv = { rv[22:0], diff[47:46] }; diff={ diff[45:0],2'b0}; if( {...

    Pipelining to make the circuit work faster

    /The circuit synthesizes for 2 Mhz clock need to make it synthesize able for 200 MHz clock // This module calculates the positive circle coordinate Y given X // with a radius of R // It is not very well written, but this provides students with // an opportunity to improve the design :-) //...
