RePlAce Global Structure

MODULE

• instances that should be placed.

  FPOS pmin; // lower left coordinate
  FPOS pmax; // upper right coordinate
  FPOS size; // (pmax.x - pmin.x) , (pmax.y - pmin.y)
  FPOS half_size; // 0.5*(pmax.x - pmin.x) , 0.5*(pmax.y - pmin.y)
  FPOS center; // 0.5*(pmin.x + pmax.x), 0.5*(pmin.y + pmax.y)
  FPOS *pof; // pin offset array.
  PIN **pin; // pin pointer's array. Save the PIN* pointer from pinInstance
  prec area; // size.x * size.y
  char name[255]; // name variable
  int idx; // moduleInstance's index
  int netCNTinObject; // net counts
  int pinCNTinObject; // pin counts
  int flg; // 
  int tier; // tier information. (only used in 3D)
  int mac_idx; // macro index. 
  int ovlp_flg; // 
  POS pmin_lg; // ?
  POS pmax_lg; // ?
  

TERMINAL

• instances that are fixed.

  FPOS pmin; // lower left coordinate
  FPOS pmax; // upper right coordinate
  prec area; // size.x * size.y
  FPOS size; // (pmax.x - pmin.x) , (pmax.y - pmin.y)
  FPOS center; // 0.5*(pmin.x + pmax.x), 0.5*(pmin.y + pmax.y)
  FPOS *pof; // pin offset array.
  PIN **pin; // pin pointer's array. Save the PIN* pointer from pinInstance
  char name[255]; // name variable
  int idx; // termInstance's index
  int netCNTinObject; // net counts
  int pinCNTinObject; // pin counts
  int IO;  // I -> 0; O -> 1
  bool isTerminalNI; // true --> have no size, false --> have nonzero size
  prec PL_area; // ?
  

NETS

• net information.

PIN

• instances' pin.
