Node highlighting aids mixed-signal
design
Tanner EDA has been demonstrating a key upgrade to its L-Edit Pro analogue/mixed-signal layout tool for IC design at DAC 2004.

Budget entry to IC layout and verification
L-Edit Pro V11 is the latest version of the analogue and mixed-signal design software for IC, MEMS and optical design from Tanner EDA.
Global foundry support for IC design tools
Users of Tanner EDA mixed-signal design tools now have easy access to X-Fab IC fabrication facilities following the introduction of support for the tools in free development kits from the foundry.
For example, the connectivity rules for metal layers can be applied and a node highlighted by selecting Metal 1 geometry.
Where layout versus schematic verification (LVS) is being performed, discrepancies between the schematic netlist and the extracted netlist are highlighted in the layout, enabling the differences to be rapidly identified and debugged.
Increase in design size is inversely proportional to decrease in verification time, with larger designs showing processing speed improvements of up to 22%.
Although DRC debugging often takes more total time in the design process, LVS debugging is usually more complicated, with each individual fix taking a relatively long time.
Node highlighting in L-Edit v11.1 improves design productivity significantly during LVS.
For example, when the LVS indicates an open circuit between two nodes, the nodes can be highlighted to determine where they are in close proximity - the most likely point at which a connection may have been intended.
Where accidental short-circuits occur, highlighting the node incrementally helps determine where the crossover to another node occurs.
The tool can also identify the shortest path between two nodes, help with visual analysis of crosstalk, and carry out certain signal integrity checks.
L-Edit Pro v11.1 will be available from 1st July 2004 priced at $16,500 for a single user licence.
