Method Detail

getEmitter

public PBlockGenEmitter getEmitter()

Returns:

A Qt Jambi-style emitter for the PBlockGenerator

generatePBlockFromReport2

public ArrayList<String> generatePBlockFromReport2(String reportFileName,
                                                   String shapesReportFileName)

main_testing

public static void main_testing(String[] args)

generatePBlockFromReport

public ArrayList<String> generatePBlockFromReport(String reportFileName,
                                                  String shapesReportFileName)

checkFreeResources

public int checkFreeResources(HashMap<Integer,Integer[]> clbPBlock,
                              HashMap<Integer,Integer> xl,
                              HashMap<Integer,Integer> xr,
                              HashMap<Integer,Integer> yu,
                              HashMap<Integer,Integer> yd,
                              HashMap<Integer,Integer> instCount)

Function takes as input one pblock (multiple if pattern repeats) and checks whether this is already used by other IPs and How many free resources (= rows) are left

Parameters:

clbPBlock - Key is simply an integer to go over all patterns. 0 should always be the first one to be chosen in the main code, as it shall avoid edge effects. Value is an array holding all the pblocks for a given pattern

xl - Leftmost columns of the pblocks

xr - Rightmost columns of the pblocks

yu - Upper rows of the pblocks

yd - Lowest rows of the pblocks

instCount - Number of IP instances

getAlreadyGenPBlocks

public int getAlreadyGenPBlocks(HashMap<Integer,Integer> xl,
                                HashMap<Integer,Integer> xr,
                                HashMap<Integer,Integer> yd,
                                HashMap<Integer,Integer> yu,
                                HashMap<Integer,Integer> instCount)

Read PBlock File for obtaining already generated pblocks

Parameters:

xl - Leftmost columns of the pblocks

xr - Rightmost columns of the pblocks

yd - Lowest rows of the pblocks

yu - Upper rows of the pblocks

instCount -

Returns:

The line number of already generated pblocks

main

public static void main(String[] args)
