    Floorplanning algorithm data structure

    why does floorplanning algorithms use b-trees? why not use other self-balancing trees?

    [SOLVED] What is the format of this netlist

    i have the following netlist input example file for floorplanning: Moderator action: removed link to external file server MODULE bk1; TYPE GENERAL; DIMENSIONS 336 0 336 133 0 133 0 0; IOLIST; P_0 PWR 175 0 1 METAL2 CURRENT 0.003 VOLTAGE 2.000; P_1 PWR 105 0 1 METAL2 CURRENT 0.003...

    Non-slicing floorplan?

    i'm trying to implement my own floorplanning algorithm. this is what i got after running it on given blocks now i'm trying to construct the corresponding tree (again see in the picture) but i'm stuck. am i putting the 'W' (wheel) node correctly? is it really a wheel? the "6, 10, 12" blocks...

    what are the inputs and outputs for floorplanning?

    i will try to ask someone to show me how it works. i just googled "integrated circuit pin diagram". i guess i need pin info to place the modules that need to be connected with their corresponding pins, close to the edges of the chip surface. - - - Updated - - - seems like i was again talking...

    what are the inputs and outputs for floorplanning?

    okay. so when i get pin info, also say i have die size info, how would i use the pin info? do i need it to eliminate the space for pins from die size, and then start doing the floorplan?

    what are the inputs and outputs for floorplanning?

    does that mean that i need to parse the netlist to get the pin info?

    what are the inputs and outputs for floorplanning?

    i found this question which answers my question: https://www.edaboard.com/showthread.php?138339-what-is-the-inputs-and-outputs-of-floorplan-and-power-plan however, i'm not clearly sure about what i need to do. for a uni project i'm writing a software (from scratch) to do floorplanning. what i...

    Circuit iterative partitioning algorithm

    okay, i got how this is done. but what are the k-l, f-m and g-b methods?

    Circuit iterative partitioning algorithm

    i have an example of iterative partitioning of the circuit. this is the formula for calculating values for iterative partitioning: Dij = Di + Dj - 2rij -> max; Dij > 0 Di(j) = Di(j)[external] - Di(j)[internal] then given this graph: these two calculations are done: D12 = (2 - 1) + (3 - 1)...

    Get n msb and lsb bits

    Re: get n msb and lsb bits hmm. are those 2 really better solutions? i mean, bitwise operations are much faster than any other operation, let alone a for loop executing 16 times. and i still don't get what is the purpose of this array or union. my register storage is itself an array of bytes.

    Get n msb and lsb bits

    hi i'm writing a program in c++ where i have registers. they are 8 bit each. however, i may have values bigger than 255, in which case i need to place the value in say 2 registers if it has 16 bits, 3 registers for 24 bits etc. so i need to extract first 8 bits (which for me are msb) and...

    shmoo plot for testing

    i have a task - generate shmoo plot from a matrix (of doubles), given the scale and step (in how many submatrices to divide the original matrix). i only know that i should calculate the average of each submatrix, i.e. suppose the big matrix is my input and step is 3, so the matrix of...

    concatenating bits example

    what i wrote was the option chosen as correct answer in a test question, i guess it's just wrong. and okay, i get it now. there's another option with your result which should be the correct result. thanks
