Welcome, LPDDR4!

Welcome, LPDDR4!
by Eric Esteve on 04-23-2014 at 3:46 am

Thanks to memory controller expert Marc Greenberg, Marketing Director for DDRn Controller IP with Synopsys, for this post “Qualcomm announces first application processor with LPDDR4 capability”. According with Marc, this Application Processor, the Snapdragon 810, is “the first product that I’m aware of that will use LPDDR4… Read More


Learning an HDL Simulator

Learning an HDL Simulator
by Daniel Payne on 04-23-2014 at 1:52 am

Learning an HDL language or an HDL simulator are two different things, so I wanted to see what was available for learning a vendor-specific HDL simulator. I’ve already taught Verilog as an instructor using both ModelSim and Active-HDL simulators, however we only used a handful of commands in the class and labs in order to … Read More


You didn’t say it has to work

You didn’t say it has to work
by Don Dingee on 04-22-2014 at 8:00 pm

“Failure to plan is planning to fail.” If that is true – and it has been quoted verbatim or slightly modified so many times throughout modern history, there has to be some truth – why does most of the engineering community seem to detest planning so much?

Engineering planning doesn’t mean whipping out a block diagram or pseudo code,… Read More


Importance of Data Management in SoC Verification

Importance of Data Management in SoC Verification
by Pawan Fangaria on 04-22-2014 at 6:00 am

In an era of SoCs with millions of gates, hundreds of IPs and multiple ways to verify designs through several stages of transformations at different levels of hierarchies, it is increasingly difficult to handle such large data in a consistent and efficient way. The hardware and software, and their interactions, have to be consistent… Read More


Ten Innovative Debugging Techniques – Pre & Post Layout

Ten Innovative Debugging Techniques – Pre & Post Layout
by Pawan Fangaria on 04-21-2014 at 8:00 pm

In a complex world of SoCs with multi-million gates and IPs from several heterogeneous sources, verification of a complete semiconductor design has become extremely difficult, and it’s not enough. In order to ascertain the right intent of the design throughout the design cycle, debugging at various stages of the design cycle… Read More


Cadence Acquires Jasper

Cadence Acquires Jasper
by Paul McLellan on 04-21-2014 at 4:06 pm

Cadence announced today that it is acquiring Jasper Design Automation for $170M in an all-cash offer. Jasper has $24M in cash so it is really an acquisition for around $145M. i think that is around 4X revenue but I only know rumors about Jasper’s revenue numbers.

All the big 3 already have their own formal technology but the … Read More


Can the NSA Get Into Your Chip?

Can the NSA Get Into Your Chip?
by Paul McLellan on 04-21-2014 at 2:49 am

At DVCon Lawrence Loh and Viktor Markus Purri gave a tutorial on Formally Verifying Security Aspects of SoC Designs. Lawrence is the direector of WW application engineering and Markus is an FAE who specializes in security verification.

I’m not going to attempt to summarize an entire half-day tutorial in under 1000 words,… Read More


International Workshop on Logic and Synthesis

International Workshop on Logic and Synthesis
by Paul McLellan on 04-20-2014 at 12:54 am

There are always a number of other events that are colocated with DAC. One this year is the 23rd International Workshop on Logic and Synthesis (IWLS) that is held the weekend before DAC on May 30th and June 1st. Strictly speaking it is not colocated since it is in the Galleria Park Hotel on Sutter Street a few blocks away whereas DAC itself… Read More

EUV Slips a Year Per Year…Or More
by Paul McLellan on 04-19-2014 at 1:54 am

I was at EDPS in Monterey the last couple of days. It is one of the most interesting conferences to attend. Go next year since you already missed it this year. It is not big but the quality of the content is high. Historically the dinner in the middle is in the Monterey Yacht Club and there is a keynote speech. A few years ago it was me but this… Read More


Power and Thermal Simulation in ESL Verification Flows

Power and Thermal Simulation in ESL Verification Flows
by Daniel Payne on 04-18-2014 at 8:11 pm

At the recent DVcon there was a keen focus on design verification and validation. Much of the attention is on Logic/circuit design verification, UVM, and IP verification. At the system level functional verification has improved to comprehend complex hardware and software interaction using Virtual Platforms/SystemC and Transaction… Read More
