SAN JOSE, Calif. Rubicad Corp., a seller of process migration tools, has introduced a layout optimization add-on to its Ladee design environment.
The HierO (pronounced "hero") add-on analyzes and evaluates a hierarchical layout and calculates how much each cell contributes to a design's total area.
Michael Rinehardt, president of Rubicad, said designers will use the tool after performing a hierarchical migration of memory designs, memory compilers or data path designs to find out what impact the reduction of specific cells have on their overall design size.
"Hierarchical layouts such as RAM, ROM or Datapath typically require cells that have certain size requirements," said Rinehardt. "When you do a conversion, compaction or layout, sometimes the cells will not conform to those size requirements. Oftentimes this is because a cell is in the wrong location in the layout. Prior to this release, you had to find the cells manually, which was very time consuming."
Rinehardt said the HierO tool tells Ladee users how close the migrated design is to reaching its optimum area, identifies any restricting cells, pinpoints them in the user's design, and lists possible reasons for the cell restrictions.
HierO is priced at $28,000 and runs on Sun, Hewlett-Packard and Pentium workstations under Sun OS, Solaris, Linux or HPUX. Rubicad will ship the tool in November.
