  11 The timing analyzer \fBtas\fP reports all critical
  12  paths between two reference points in
  13 a file, named 'general perfmodule'. The file has the extension .ttx.
  14 This is a highly compact
  15 text format suitable for flat and hierarchical analysis. The content is best
  16 visualized by ETAS or XTAS.
  17 The 'detailled perfmodul' has the extension .dtx.
