Complex, Digital Printed Circuit Board with Radio

Application
Networking Communications

Customer Need
A new start-up company faced with a critical time-to-market schedule to introduce a new product at an industry trade show required on call services to meet schedules.

AVID’s Solution
AVID provided complete library development to IPC-7351A standards and PCB layout and simulation services for signal integrity verification of DDR2 memory. Within the layout, AVID utilized high-speed processor/dual DSPs, each with DDR2 memory, and applied extensive attention to thermal management. The radio layout proved extremely challenging due to the small form factor. The unit was completed and demonstrated successfully, leading to a promising new product introduction.

Value Added or Technologies Applied

  • Impedance Controlled
  • Pre-Layout Simulation
  • Length Matched Constrained Routing
  • Thermal Planning

Application
Custom Computing System

Customer Need
Customer’s engineering team required expertise in PCB layout of a controller board with large FPGAs, DDR, giga-bit Ethernet, USB and compact flash. The engineer responsible for the project relied primarily on AVID for development of routing constraints for circuit function and performance.

AVID’s Solution
Utilizing our expertise from completing hundreds of printed wiring board layouts, AVID was able to fully define the routing constraints as well as optimize the stack-up for improved signal integrity. AVID was also able to identify several schematic connection issues and improvements that were able to be corrected before the layout was completed. Ultimately, AVID saved considerable time and money for the customer by avoiding costly board fabrication re-spins and multiple assembly cycles.

Value Added or Technologies Applied

  • Controlled Impedance
  • Pre-Layout Simulation
  • Design Rule Constraints
  • Post-Layout Crosstalk Analysis

Customer Need
Beta release of board level product experiencing random DDR2 data errors from unknown causes.

AVID’s Solution
After initial discussion and a characterization of the problem with the customer, AVID proposed a two pronged effort that would involve review of all the important board level strategies for proper performance while also providing simulation services to determine root causes of the problem and optimization of the best solutions.

Within a short period, through interaction with the customer’s technical staff, improvements to the initial customer approach were identified and required changes defined. After edits implementing the new topology and optimized values were complete, post simulation was performed to confirm results.

Follow on testing supported expectations and a reliable product was ready for the next phase.

Value Added or Technologies Applied

  • Review and report on current PCB signal integrity planning and routing implementation
  • Memory architecture, topology and components review with suggested solutions
  • Processor memory interface initialization registers review
  • Signal integrity simulation, both pre-solution and post-correction confirmation
  • Follow on support through testing approval and release
