DES PLAINES, IL - PCB Matrix Corp. has released the PADS Layout Constraint Rules Editor. The software is used with PADS V5, V2004, V2005 and V2007, and optimizes the use of constraint set-up and rules within PADS Layout.

The company states that the constraint rules editor interface allows users to view, change and update rules, with easy transfer of updates between the PADS Layout tool and constraint rules editor.

The company reports that using PADS software, you can specify separate rules for clearance and trace width for individual pin pairs, nets, groups of nets, classes, components and even the entire design, with the flexibility to control the length of critical nets or specify matched lengths for groups of nets.

STOKE ON TRENT, UK - PCB design bureau Black Stick Ltd. has a free software tool called the C4Calculator. The tool calculates current capacity for a given PCB track width and thickness. Black Stick’s C4Calculator (Current Carrying Capacity Calculator) utility determines the optimum current based on a given interconnect width and thickness. In addition, C4Calculator will also calculate the gap needed between conductors for a given voltage peak. All the calculations within the tool are taken from formulae or tables specified in the IPC-2222A standard. C4Calculator also allows users to perform calculations beyond the scope of the IPC standard.

FLINTSHIRE and BERKSHIRE, UK - PCB Design Service provider companies Routability and Total Board Solutions (TBS) have partnered to develop a training course based on Mentor Graphic's Expedition PCB software specifically for PCB design contractors.

"We have coped with demand to this point," commented Ben Dowding of Routability, "but we have already been asked by other service providers, on more than one occasion, if we could supply contractors to them. As the demand for Expedition grows, so the opportunities for contractors will increase."

Sue Critcher of TBS adds, "Getting to grips with the basics of any EDA software… requires training and experience. We approached Mentor Graphics about our concerns and …based on the latest EE2007.1 Expedition PCB flow, we have developed a three-day training course for contractors"

ST. LOUIS, MO – Laird Technologies, Inc has introduced an advanced 3D simulation tool for electronic design. The company is currently using the product for 3D simulations in the design of mobile devices and antenna systems.

Utilizing Ansoft Corp.’s HFSS DSO design tool, Laird Technologies can now create designs and evaluate design concepts that were previously too complex to simulate.

According to Blaine Bateman, Laird marketing VP, “The ability to simulate effects of multiple antennas coupled to other subsystems in the device is critical for…live video, high data rate transmission, interactive web surfing, and other wireless Internet capabilities.”

“Our DSO design tool represents the next evolution in high-performance design improvements for solving very large problems in 3D mesh-making, solution capacity, and memory management,” said Dr. Zoltan Cendes, Ansoft CTO.
