FAQ   CAST White Paper Download   Prev 1 2 3 4 5 Next Why aren't there any design rule references in your sample PyCell code？ Ciranova Inc. The sample PyCells are deliberately authored without reference to technology rules. Ciranova's RuleWise Technology allows you to separate rules from geometry, so you can focus on layout intent. Click here to learn more.   We've used the proprietary language which comes with our layout editor to write PCells for many years. Why should we switch？ Ciranova Inc. Some PCell developers want their PCells to support internal tools, or tools from another EDA vendor. Others need support for conditional rules. You may find that the complexity of your PCells has grown beyond what you can handle with a legacy language. Or you may just want to use an industry-standard language like Python, which is supported by a wide range of commercial and freeware tools, books, training, and services. PyCells and legacy PCells can coexist in one library and in one design, so you can develop new PCells as PyCells without having to re-write existing PCells that you wish to maintain going forward.   I have written script code in SKILL to manipulate PCells in a DFII environment. Will this code work with PyCells without modification？ Ciranova Inc. SKILL scripts that create or manipulate PCells in design databases can instantiate PyCells just as easily. No modifications are required to the SKILL scripts.   Can we release a library that uses your sample PyCell code？ Ciranova Inc. Yes. Please see our End User License Agreement（PDF）License Agreement for the specific terms.   What EDA tools have been tested with PyCells？ Ciranova Inc. PyCells can be used with OpenAccess 2.2 compliant tools from any vendor, including internal tools. Check with your tool provider to find out when your tools will support OpenAccess. Ciranova tests compatibility with OpenAccess tools from vendors who provide software to our testing lab.   Can PyCells and PCells written in a vendor's legacy language coexist in the same OpenAccess database？ Ciranova Inc. Yes.   All I want to do is design a chip using a PyCell library I was given. What do I need and how much will it cost？ Ciranova Inc. If you are using OpenAccess-compliant design tools, you can download everything you need for free from our download page. All you need to open a PyCell library and instantiate PyCells is an OpenAccess PCell plug-in which is included in the free download kit.   What else do I need to use PyCells, in addition to your software？ Ciranova Inc. You will need an OpenAccess-compliant layout editor to design a chip using PyCells. Among the many compatible products are Cadence Virtuoso 6.x, AWR Analog Office, Synopsys Galaxy Custom Designer, or Springsoft Laker and MicroMagic Max.   How do I instantiate PyCells in my design？ Ciranova Inc. The same way that you instantiate other PCells, using the same dialog boxes and commands available in your favorite. A PyCell library is just another library to an OpenAccess-compliant layout editor.   How can I use my SKILL PCells in OpenAccess tools other than Virtuoso？ Ciranova Inc. PCell Xtreme enables OpenAccess tools from multiple vendors to read and parameterize your existing SKILL PCells. It also speeds up the time required to open a database containing PCells by 10X or more. If you want to use your existing SKILL PCells in OpenAccess tools from multiple vendors, you need PCell Xtreme.
