Here is a listing of some of the important updates made to IC6.1.8 and ICADVM18.1 for the ISR4 release:

• New Automated Device-Level Layout Flow (ICADVM18.1 Only)
  Use the Auto Device P&R assistant to generate automatically placed and routed layouts.

• Generation of Reusable Modgen Templates (ICADVM18.1 Only)
  Increase your layout productivity with the use of reusable Modgen templates that comprise a set of common Modgen parameters that can be reused to create a gridded layout of matching structures.

• Support for Stack Devices in Modgens (ICADVM18.1 Only)
  Use the GPE and GPM assistants to visualize and manipulate stack devices within Modgens to achieve higher circuit performance goals in advanced node PDKs.

• Trunk Mesh Routing Flow (ICADVM18.1 Only)
  Use the new Trunk Mesh Routing Configuration form to configure trunk to trunk mesh routing for a Layout EXL device-level design.

• Tree Routing Flow (ICADVM18.1 Only)
  Automatically identify and route mesh, ring, and tree structures in advanced node device-level designs using the new Tree Route Flow.

• Automatic Trunk Generation Using the Trunk Subform (ICADVM18.1 Only)
  Now generate trunks automatically for device-level designs using the trunk generation option under the Generation group box of the Trunk subform.

• Top-level Editing of Virtual Hierarchy Clones (ICADVM18.1 Only)
  Perform basic edits at top level—stretch, chop, and area boundary adjustment—for a virtual hierarchy clone.

• Support for Deleting Color of Connected Shapes (ICADVM18.1 Only)
  Use the Delete color on connected shapes option on the Multiple Patterning Options form to delete the color on shapes connected to the selected shape.

• Color Locking of Synchronous Clones (ICADVM18.1 Only)
  Use the Lock Colors drop-down in the Multiple Patterning toolbar to lock (or unlock) all colors on all (or selected) layers.

• Support for Instance-Level Local Scoping
  Use the MTS Options form to now enable local scoping at an instance level.

• Support for New EM Data Source
  Use the iRCX-EM file as a new data source for EM without needing to update the existing EAD technology file or first converting to an ICT-EM file.

• Enhanced EM/IR Analysis for Wide Pins
  Specify multiple current injection points on wide metal pin for accurate EM and IR drop analysis.

• Support for Maintaining the PDK Version for Express Pcells
  Define a library version SKILL variable in the libInit.il of a PDK to be notified if Pcells currently in the cache are out of date.

• Support for Enabling Express Pcells for Specific Libraries
  Control which Pcell libraries are included or excluded for cache operations.
