As feature sizes decrease there is a growing need for chemical-mechanical polishing (CMP) modeling to better understand how the design layout impacts planarity. CMP modeling has proven to be very effective in simulating the profile when a process has a well-defined physics based model. In this IC … [Read more...]
Adopting an Interface DRC Checking Flow
Chip-level physical implementation teams must manage top-level physical verification from the early floorplanning stages through tapeout. In early floorplanning, blocks placed in the chip-level floorplan may still be under development. Merging these incomplete blocks with the chip-level interconnect … [Read more...]
Integrating Pattern Matching with DFM Properties to Enhance and Optimize Layouts
In this IC design white paper we explore how the use of pattern matching has expanded into design for manufacturing (DFM) flows and integrates with different types of DFM properties (numeric, strings and vector properties). Leveraging these properties in pattern matching allows for several new … [Read more...]
Achieving Optimal Performance During Physical Verification
With increased complexity in design layout requirements at each new node, the compute burden placed on physical verification has grown exponentially. At the same time, designers are generally faced with less time to get their designs out the door. In this white paper, we detail the key steps you … [Read more...]
Color Optimization Considerations in Multi-Patterning
Decomposing multi-patterned design layers into colors has traditionally been an exercise in finding at least one DRC legal coloring solution. In this white paper we discuss how manufacturers at more advanced nodes are now finding significant yield and performance differences among DRC legal coloring … [Read more...]
Proof-of-Concept: The Day After
The day after creating a proof-of-concept of your custom IC, you might ask “Now what do we do?” It is time to make your idea real and start developing a system prototype. While the proof-of-concept activity answers the question, “Is it possible?” the prototype answers the question, “Can the system … [Read more...]
18th Century Technology for Modern Medical IoT
Back in 1790, Luigi Galvani was dissecting a frog and noticed that he could cause its leg to move when touching a nerve with two probes. He called this phenomenon “animal electricity.” This concept was soon refined over time to become the voltaic cell, the foundation concept of the potato clock, … [Read more...]
Effects of Incorporating Hysteresis in the Simulation of Electromagnetic Devices
An important consideration in electrical machine and transformer design is the magnetic flux in the ferromagnetic cores. Simulation accuracy is dependent on realistic material models that reproduce the expected magnetic behavior. This paper describes the use of an advanced hysteresis material … [Read more...]
Effects of Demagnetization in EV Electric Motor Simulations
The use of permanent magnets is increasing in modern electrical machines because of the need for reduced size and higher performance. An important consideration in electrical machine design is the demagnetization of these magnets due to high currents and temperatures. Simulation accuracy is … [Read more...]
Computer Vision Sees a Bright Future
Computer vision is powering advances in automotive, medical, consumer, and agriculture markets. Because the world of computer vision coupled with machine learning evolves so quickly, teams need a way to design and verify an algorithm while the specifications and requirements evolve without starting … [Read more...]
