I had a chance to speak with Dr. Pole Shang Lin, CEO and President of EverCAD Navigator Company. The material below is based upon that conversation and various written materials provided by the firm.
US subsidiary of EverCAD Software Corp.
EverCAD was founded in 1998. It is a private, self-funded company. The firm has 20 people overall split between Fremont, California and the Science-Based Industrial Park in Hsin-Chu, Taiwan, R.O.C. The installed base consists of approximately 70 customers with over 200 licenses sold. The customers are in the US and in Asia. Among these customers are UMC, Cisco, LSI Logic, MediaTek, Chartered Semi, Mstar Semiconductor, InProComm, Faraday Technology, SiS, Archband Labs and Silicon Bridge.
The company sells direct in the US and Taiwan and through distributors in Korea and Japan. EverCAD has no customers as yet in mainland China. Protection of intellectual property rights is a concern in that country.
ADiT-Turbo is an all-in-one advanced circuit simulation tool suite for full chip and SoC designs in analog, mixed mode, and multi-level environment. It features revolutionary single engine architecture, coupled with a superior set of user-friendly, accuracy, speed and performance. With partition algorithm and simplified matrix solver, ADiT-Turbo can simulate large circuit with simulation speed 10X~ 100X faster than that of SPICE.
EverCAD offers ADiT in an OEM package, although Dr. Lin would not identify any current customers.
DIAMOND is designed for circuit level verification of designs with more than a million gates, including mixed-signal, SoCs, video and network processors, DSPs' Flash, SRAM, DRAM, CAM and other memory like structures. DIAMOND's inherent strength is in its ability to accurately simulate Delta-sigma, ADC/DAC, switched-capacitor filters, PLLs, charge pumps, high-speed transceivers and large analog designs which require long simulation times when using SPICE tools.
With DIAMOND EverCAD is targeting three areas. 1) Top-Down designs which need detailed timing and power verification. 2) RAM-compiler users. 3) Complex mixed-signal SoC design engineers.
DIAMOND will be available on all major platforms including Solaris, HP-UX, Windows, and RedHat Linux including Red Hat Enterprise Edition.
Pricing for DIAMOND is around $150K. ADiT pricing was $100K to $130K depending upon the modules licensed.
Dr. Lin says that EverCAD target markets are high speed IO, power management, high-resolution AD/DA, and mixed-signal SOC design. He identified Nassda as the firm's principal competition and claimed that EverCAD provides a more accurate solution.
He believes that the major problem is interface and that interface is a purely artificial element. He believes that this is an important issue for customers and that EverCAd has solved the problem. The current approach for mixed signals between analog and digital blocks are through two A2D and D2A behavior devices. The user needs to specify some parameters such delay-time, rising-time, falling-time, driving resistance before simulation. This may cause accuracy problem for some high-speed design. DIAMONDS creates this automatically.
The product can be used for simulating small blocks during the design phase and at tapeout for full chip verification: function, timing and power.
Diamond provides a complete functional, timing and power analysis solution for analog mix signal designs verification. Our solution not only provides an easy of use environment, but also with performance and accuracy.
In particular Dr. Lin pointed to a customer success story based on Archband Labs's mixed signal design of 24bit delta sigma audio ADC with clock generator and DSP. Without using behavior models, designers can perform full-chip simulation by combining SPICE and Verilog parts together for more reliable and accurate verification. Previously analog and digital designers verified only their own piece of the design.
EverCAD has two beta sites for DIAMONDS and expects the product to be available the end of this quarter.
On the litigation front Synopsys filed two additional suits against Magma on September 26. We had covered the original suit in considerable detail in our June Editorial, entitled
Magma-Synopsys Litigation. One of the new suits is a claim of unfair competition against Magma based upon Magma's action in defending itself in the patent case, while the other deals with additional patent infringement. At least one of the patents in questions comes from Synopsys' acquisition of Monterey Design Systems.
these egregious tactics to defend a declining market position against an up-and-coming innovator like Magma. I can only hope this strategy is the result of a legal team out of control. “
