Empyrean SPICE min

A familiar face in EDA, Greg Lebsack met with me in the Empyrean booth at DAC this year on opening day to provide an update on what’s new. I first met Greg when he was at Tanner EDA, then Mentor and Siemens EDA, so he really knows our industry quite well. The company was a Silver level sponsor of DAC this year, and Empyrean offers tools for… Read More

Patron EM IR flow min

I arrived for my #60DAC booth appointment at Empyrean and was able to watch a customer presentation from Jason Guo, of Diodes. Jason was talking about how his company used the Patron tool for EM/IR analysis on their automotive chips. Diodes was found back in 1959 at Plano, Texas, and has since grown into 32 locations around the globe,… Read More

PMIC Design SemiWIki

Power management integrated circuits (PMICs) are integrated circuits for power management. Driven by the strong demand in consumer electronics, IoT, and the automobile industry, the design for PMIC is getting more challenging in terms of integration, reliability and efficiency. The design methodology needs to be updated… Read More

iWave waveform min

Automotive electronics bring strong demand for power management chips, but its strict reliability requirements also pose new challenges for chip designers. The chip needs to be able to work in various harsh environments such as high temperature, low temperature, aging, abnormal power supply, etc. Although the traditional… Read More

Speed Up LEF Generation Times on Huge IC Designs
by Daniel Payne on 06-03-2021 at 10:00 am

GDSII and LEF min

For IC designs there are many data formats used throughout the logical and physical design process, and one of those file formats is called LEF, an acronym for Library Exchange Format, created by Tangent, an early EDA company with Place and Route tools that was acquired by Cadence way back in March 1989. LEF generation times can become… Read More

FPD voltage distribution analysis min

This area of automating the design of Flat Panel Displays (FPD) is so broad that it has taken me three blogs to cover all of the details, so in brief review the first two blogs were:

My final blog covers five areas:

  • DRC/LVS for curvilinear layout
  • Circuit

Empyrean - FPD design flow

I’ve used OLED (Organic Light-Emitting Diode) displays for many years in my monitors, laptops, tablets, e-readers and smart phones; and knew that the AMOLED (Active-Matrix OLED) displays used thin-film transistor technology where each pixel can be controlled, but I hadn’t considered the actual design process… Read More


Xilinx Moves from Internal Flow to Commercial Flow for IP Integration

Xilinx Moves from Internal Flow to Commercial Flow for IP Integration

Xilinx IP min

I’ll never forget first learning about Xilinx when they got started back in 1984, because the concept of a Field Programmable Gate Array (FPGA) was so simple and elegant, it was rows and columns of logic gates that a designer could program to perform any logic function, then connect that logic to IO pads to drive other chips … Read More
