Answers to Top 10 Questions on Performing ECOs in EDI System
Applying ECOs to a design can be complex, stressful and error prone so it's important to apply the right tools and flow to implement the changes successfully. EDI System provides multiple ECO flows to physically implement ECOs efficiently and accurately based on your design requirements. And adding...

Why Multi-Mode, Multi-Corner (MMMC) ECO Closure Requires a New Signoff Approach
In the semiconductor design flow, engineering change orders (ECOs) are as inevitable as death and taxes. While this has always been the case, ECO timing closure is becoming increasingly difficult as the number of operating modes and process-voltage- temperature (PVT) corners skyrockets. What's needed...

ENCOUNTER ECO - module
Hi, we use encounter to implement most of our ECO's. However, we have an ECO which requires too many gates. We have heard that some people rip out a module, and have the tool replace the module with the new netlist. The question is what is the procedure to do that? It is easy enough to locate the...

High-Level Synthesis Users: Productivity Gains Beckon, But Learning Curve Comes First
SystemC-based high-level synthesis (HLS) tools have greatly improved in recent years and are undergoing adoption by many large semiconductor companies. But to get high productivity out of HLS, current RTL designers will first face a learning curve, according to panelists at the recent Design Automation...

A Quick Tutorial on Managing ECOs Using Pcells in Mixed Signal Designs
The purpose for creating a Pcell is to automate the creation of data. Pcells should be designed as standalone entities, independent of the environment in which they are created and independent of the variety of environments in which you or someone else might want to use them. An environment can react...

Managing ECOs in Mixed Signal Designs
Imagine you are days away from completing the implementation of a fairly complex mixed-signal design, and you are already day-dreaming about the vacation you have planned in a few weeks. Then it happens -- the dreaded change in the design requiring ECOs to digital or analog content, or worse yet, implementation...

spare logic is not tied up/down properly after ECO route
In my ECO step, a number of logic gates are freed up and become spare gates. They should be connected to VDD or GND selectively. What command should I use? The large majority are grounded, but a few are tied high. Note: I don't have tieHi or tieLo cells in my library; I want to hook up directly....

System Development Suite - Connecting Software to Hardware Design and Verification
I've been at CDNLive! EMEA watching demos of the newly announced System Development suite, and it's mindblowing. I'm seeing good old ncsim running Android interactively on the Virtual System Platform. You open an app in the virtual Android interface and you can stop the software, or even...

Q&A: What Designers are Finding at 28nm – and How a “Unified” Digital Flow Can Help
Early adopters are starting to design at 28nm and are running into some challenges, according to Rahul Deokar, product management director for digital Silicon Realization at Cadence. In this interview he talks about challenges designers are experiencing due to design rules, lithography, low power, mixed...
