Upgrade for mixed-signal IC design platform

Edited by the Electronicstalk editorial team Apr 14, 2005

L-Edit v11.1 is the latest release of the flagship analogue and mixed-signal IC design platform from Tanner EDA.

Tanner EDA has released L-Edit v11.1, the company's flagship analogue and mixed-signal IC design platform.

This newest release includes node highlighting functionality that allows users to display all the geometry connected to a node in a circuit layout, regardless of hierarchy.

Users can rapidly identify and debug differences between layout and schematic netlists by using LVS (layout versus schematic) which displays discrepancies between the schematic and the extracted netlist from the layout.

Verification productivity has been enhanced proportional to design size; v11.1 can process larger designs up to 22% faster.

A representative circuit of more than 2.2 million devices now loads in less than 8min, using about 400Mbyte of RAM.

Also, v11.1 includes support for large format printers and optional plot decorations such as custom header, ruler and layer indicators.

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.

Although DRC debugging often takes more total time in the design process, LVS debugging is usually more complicated, with each individual fix taking a correspondingly longer time.

LVS performance is significantly improved, especially in merging series devices including MOSFETs.

Other new features of L-Edit v11.1 are enhanced design rules checker that allows the user to customise the colour in which specific violations are displayed, and a number of new UPI commands have been added.

L-Edit V11.1 is available now.
