Many of you already received communications about the move of the Cadence user community into cadence.com. And many of you have already joined, with over 4000 registrations in the first two weeks.

The new Cadence Community enhances the ability of Cadence users to connect and collaborate. In addition to moving the community into cadence.com -- enabling single sign-on for community, Sourcelink and Cadence events -- the new site is organized around nine technology segments, giving you easy access to product information, training, forums and blogs. Some of the new features include:
  • Ability to respond to posts via e-mail
  • Technology-specific blogs
  • Latest Web 2.0 social networking capabilities
  • Public profile options
  • Private messaging
  • Friends lists
Visit the new Cadence Community today at www.cadence.com/community and join the discussions!

Registration note: Due to the scope of the enhancements and the new SSO registration system, we were not able to migrate existing cdnusers.org member accounts. So new registrations are required, but this enables a broader set of functionality we think you'll enjoy.

Forum note: Under the guidance of forum moderators, we have taken the 20+ cdnusers.org forums and consolidated them into 11 forums on the new site. Posts have been brought over so you can leverage that posting history. CDNusers forums will be set to read only starting 7/30, and cdnusers.org will be redirected to the new community on 8/4.

Best regards,
Mike and Tom

How do you specify/create a rectilinear floorplan? I am trying to create a hard macro for a lower level block and it is rectilinear.

Thanks,

The same mechanisms used to create rectilinear partitions and fences can be used to operate on the boundary of a block-level design.

Using the GUI, switch to the "Floorplan view" and then use the "Cut Rectilinear" widget to create a rectilinear boundary. When you have the "Cut Rectilinear" widget active, your mouse pointer will become a different shape when you hover near the perimeter of the block- click once to start the cut and again to complete the cut.

This resolves to the text command "setObjFPlanBoxList":
setObjFPlanBoxList Cell {results_conv} 0.0000 182.2250 146.3400 231.8400 0.0000 0.0000 227.7000 182.2250

The coord list setObjFPlanBoxList expects is a series of "llx lly urx ury" boxes that define the rectilinear shape. In the example above, the coord list corresponds to an L-shaped rectilinear.

Thanks, I did find the cut Rectilinear in the tool menu yesterday but somehow could not get it to work. I will probably try the command directly.

The command didnt work either at the block level. Found out that the command doesnt work if there are hard macros defined as type pad. Modified the LEFs to make them type blocks and the command works ... in case someone else runs into this.
