Release Notes: This release adds a new edit in place command to allow descending the hierarchy by name in addition to the existing point based EIP command. PDF generation has added the transparent color model to the existing overlay color model. Programmable cells may now use a closed shape as a reference. Closed shapes are useful when creating a well tap isolation ring object as an example. Closed shape TLG's can be marked as splittable. There is a GIF animation on the Web site showing the result of splitting a well tap ring to allow a gap for wiring over a well tap ring.
Release Notes: This release adds a new GUI mode using a tkcon for the console instead of an xterm. The tkcon was modified to incorporate the non-window specific menubar items as well as the XY display. Other changes include a new legend option when creating PDF documents of layouts and a new option to the layer display control window to only display layers in the current layout view. Some new device generators were added to support DMOS and HVMOS structures. Lastly, the free layout viewer has a port to the raspberry pi platform.
Release Notes: This release includes new capabilities in the DRC/LVS, enabling checks of most 0.18 micron processes. A new command has been added to the editor to move objects between hierarchical levels in a single operation. The cut/paste command has been modified to have multiple buffers. Each buffer is assigned a user-defined name so you can easily select between buffers. The stream out command layer map added a new directive so you can specify a unique layer to write text associated with pin objects. With this change, different layer mappings may be assigned for geometry, text, and pin (the text part) objects.
Release Notes: This release adds substantial improvements to the DRC/LVS option. Antenna rules, an LEF generator for antenna model, rules for different net spacing, and more polygon selection criteria are just some of the additions. Also added are some new pcell definitions and pcell support functions, such as offset path generation to easily construct coaxial shielded net and guard ring structures. Lastly, a new command to join two sets of bus wire groups together, via-ing as needed to connect the pair, was added.
Release Notes: This release extends the number of layers from 4,000 to 16,300 and adds vector PDF output for small layouts and cross sectional views so layouts/cross sections can be easily exported to documents. Note that the diffusion profile in the cross sectional view can have rounded or custom profile edges. This release also updates the "add wire" command to be repelled "min" space away from other objects, to avoid DRC errors. The LVS option has been completely updated to extract any angle geometries and extract WPE/STI/NRS/NRD values. A new free gds viewer is now available for download from the website.
Release Notes: This release adds a new violation reader for ICV and a new movie mode for net tracing to replay traces at a user-controlled speed. Traces can also be saved for later playback if desired. Selection was sped up substantially when selecting large numbers (hundreds of thousands to millions) of objects. The select by name command can ignore objects that are part of a device. This allows devices that contain a match to remain unselected, for example. Large libraries are browsed more quickly. A problem with the OS when forking was when the slam process was in the tens of gigabytes has been solved.
Release Notes: This release adds a number of new devices, including MEM's gears and MEM's spirals. It is also relatively simple to animate MEM's devices to check for conflicts in their motion. Other minor changes include a new prune option in stream out to remove unused cells, the ability to include files in layer map files, reference libraries may now be Tcl expressions, and a new hierarchical, library sensitive pcell menu. The major upgrade in this release is an enhanced DRC option. Previous releases had a highly restrictive orthogonal style DRC. This release properly handles any angle objects.
Release Notes: Two minor new features were added: an inductor pcell and the ability to view a cross section of the layout. A calculator utility is also provided so the parameters for the pcell can be computed from a target inductance value. Since inductance is not linearly related to number of turns, the calculator can save a lot of guessing. The cross sectional or side viewing can be activated by entering a vertical or horizontal split line. After the line is entered, a new window showing the topology of the layout is displayed in a new window for the cut line. Large designs can be displayed very quickly.
Release Notes: This release adds a new command to compare layout cells for object differences. The new command allows you to quickly determine if a cell has been changed. Unlike an XOR, this command will also detect a difference in text objects. Other changes include modification of the inquire command to give a brief summary of the selected objects when more than one object is selected. The select command considers the origin of vias in addition to the shapes of a via. Speed enhancements were made to the DRC/LVS module. A new instance extraction mode has been added to the LVS extractor.
Release Notes: The transform command was altered to grid the result using either the window's current edit grid or the cell's min grid. The option to limit a text object's display height when zooming in was added. By limiting the text size, it is possible to read the text even when zooming to small areas. A bug was corrected in tracing when the hierarchy contained cells from multiple libraries using different technology files. Hot key handling was modified so that modifiers such as NumLock and ScrolLock can be ignored.
