    Setup time violation in front-end design

    Set-up time violation should be taken care in front-end design. As far as I know, front end deals with rtl description. How is set-up time being fixed here? Thanks in advance.

    [SOLVED] squaring a fixed point number

    i hope you got that m using a fixed point number notation in std_logic_vector. the * operator really doesn't work, because a number 1.5 is stored as "00000001 10000000" which is recognized as 384. Hence the * operation results the square of 384 but not 1.5. It's quite complicated! May be I...

    [SOLVED] squaring a fixed point number

    I have done over half my code using std_logic_vector and m stuck at this point where squaring has to be done. How can I use signed type? The removal of 8 MSBs and 8 LSBs is not a problem coz i don't work on large numbers and require only 8 bit precision. Well, 16 and 32 can be accommodated in...

    [SOLVED] squaring a fixed point number

    Hi, I have a std_logic_vector(16 downto 0) which stores a fixed point number in which, the bits (16 downto 8) store the integer part of the fixed point number and (7 downto 0) store the fractional part of the fixed point number. Now, I need to square the number to obtain the result in another...

    Effect of Radiation and heat on plasma

    It is a known fact that semiconductors short at high temperatures or ionizing radiation environments, because of the high current density contributed by the formation of new electron hole pairs. How does plasma respond under these conditions? I have read a paper that the operation of...
