Reducing analog cell layout time with the symbolic editor.

In the last blog post I profiled the use of the symbolic editor for rapid digital cell layout. In this post we will tackle analog cell layout and show some more of the symbolic editor features that enable analog layout engineers to complete their layout in minutes versus hours. As with the digital cell layout, […]

Rapid custom digital cell layout with the symbolic editor

In Custom Compiler Layout Assistants – part 1 we profiled the use of the symbolic editor and how it makes placing devices that need to be in a specific interdigitated pattern like for example a differential pair very easy. With no constraints to enter, no code to write, layout is done in minutes versus hours. […]

Custom Compiler In-Design Assistants – part 3.

In the blog Custom Compiler In-Design Assistants Part 2, I outlined how we can use StarRC to report capacitances on critical nets in the layout even when the design is still in flux and not completely LVS clean. In addition to capacitance reports we also showed resistance reporting which is critical for FinFET based layouts. […]

Custom Compiler at DAC 2016

  DAC 2016 saw the first Custom Design luncheon to feature Custom Compiler. It was a sold out event with 150 customer attendees eager to hear from Synopsys and other customers about how Synopsys is progressing in the custom design space. Antun Domic, Senior VP and General Manager of the Design Group moderated the event […]

Custom Compiler In-Design Assistants – part 2

Planning which metal shape goes on which color (mask) is key when designing in a FinFET process, especially when propagating connections through the layout hierarchy. In addition, highly matched signals such as complementary clocks must be assigned to the same color, as routes on different masks have different resistances. So how do we ensure we […]

Custom Compiler In-Design Assistants – part 1

On line Design Rule Checking (DRC) is nothing new. The technology has been in use for years in a variety of different layout editors and yet nearly every Layout engineer has a love / hate relationship with it. Why? Well it really comes down to the use model and the responsiveness of the application. At […]

Custom Compiler Layout Assistants – part 2

In the last blog I detailed the symbolic editor layout assistant and showed how the layout engineer can make simple graphical choices of how the layout needs to look and then have the placement taken care of by a placement engine. In this post I will outline another layout assistant the router. The routing task […]

Custom Compiler Layout Assistants – part 1.

On March 30th Silicon Valley was buzzing with excitement. Synopsys held the Silicon Valley SNUG event and revealed Custom Compiler, a fresh approach to custom design that employs visually-assisted automation technologies to speed up common design tasks, reduce iterations and enable reuse. During the event the R&D folks did a walkthrough of the technology ‘under […]

The wait is over!

The wait is over! Remember the last few blogs where I was outlining the kind of tools you really need to tackle FinFET? Well they are here right now, because today Synopsys unveiled Custom Compiler and ushered in a new era of Visually-assisted Automation. Check out this link: http://www.customcompiler.info It’s all the good stuff I […]

What do layout engineers really need for FinFET – part 2.

In the last of blog we outlined the kind of tool that the layout engineer needs in order to get a good placement that delivers robust working silicon within the confines of the FinFET process. We concluded that a guided / interactive approach that is fast and easy to refine such that you do get […]
