  12        Gets a selection of paths/accesss, depending upon configuration.
  13            If   _\bt_\bf  is  not  specified  then  _\bs_\bt_\ba_\br_\bt_\bn_\bo_\bd_\be_\bl_\bi_\bs_\bt,  _\be_\bn_\bd_\bn_\bo_\bd_\be_\bl_\bi_\bs_\bt  and
  14        _\ba_\bc_\bc_\be_\bs_\bs_\bn_\bo_\bd_\be_\bl_\bi_\bs_\bt are considered _\bT_\bi_\bm_\bi_\bn_\bg_\bS_\bi_\bg_\bn_\ba_\bl lists. They  are  node  name
  15        lists otherwise.
  16            The _\ba_\bc_\bc_\be_\bs_\bs_\bn_\bo_\bd_\be_\bl_\bi_\bs_\bt is used only if _\b-_\ba_\bc_\bc_\be_\bs_\bs is specified.

  22                      Path  start node list (clock node if _\b-_\ba_\bc_\bc_\be_\bs_\bs is used). If
  23                      not specified, all possible start nodes are considered.

  26                      Path access node list (latchs, precharges,  breakpoints).
  27                      Used  only  with  _\b-_\ba_\bc_\bc_\be_\bs_\bs. If not specified, all possible
  28                      access nodes are considered.
  29

  32                      nectors).  If  not  specified, all possible end nodes are
  33                      considered.

  35        -\b-d\bdi\bir\br {\b{<\b<d\bdi\bir\br>\b>}\b}  Path transitions: _\bu_\bu, _\bd_\bd, _\bu_\bd, _\bd_\bu; _\bu or _\bd can be  replaced
  36                      by  the  wildcard  _\b?.   _\bz  or _\b/ can be added to the usual
  37                      direction to respectively retreive only HZ path  or  only
  38                      non-HZ path. Default is _\b?_\b?.

  41                      list. If _\b<_\bn_\bb_\b> is negative or zero, no path  number  limit
  42                      will be considered. Default is _\b-_\b1.
  43
  44        -\b-c\bcr\bri\bit\bti\bic\bc       Returns only critical paths. This is the default.

  47
  48        -\b-p\bpa\bat\bth\bh         Searches for paths. This is the default.

  51
  52        -\b-m\bma\bax\bx          Uses  maximum delays for the search. This is the default.
