Experts at Wireless Applications & High Speed Digital Design Services

Thank you for visiting the BLT Wireless Applications High Speed Digital Design Services page.

Founded in 1985 by one of the original Xilinx Field Application Engineers, the continuing mission of Bottom Line Technologies Inc (BLT) is to offer our Clients premium quality design services on aggressive schedules at an competitive price.

We invite you to learn about our company and our philosophies to see who we are and how we get the job done. We also suggest that you visit our Wireless Applications and High Speed Digital Design Services pages for more specific information.

Because of our beginnings, BLT’s proud reputation as “The Xilinx Experts” often precedes us. However, due to the changing expectations and needs of our clients, over the years we’ve grown beyond our Xilinx roots combining the latest technologies with specialization in a variety of services to offer our clients the most reliable, expedient and economical path to market.

The Bottom Line approach is one of quality by Project Management, Design Methodology, and Project Staffing. Our mature, time proven methodologies ensure you start and finish your designs the right way, on time, and on budget. By helping our Clients avoid dozens of common mistakes, we frequently shave days, weeks or months off their schedules.

BLT also satisfies a multitude of non-technical needs of our Clients effectively allow BLT to perform as an extension of our Client's organization.

The "bottom line" is that the goals of our Clients and BLT are best achieved when designs are done well, promptly and cost effectively. Our greatest pride is our broad base of referrals and repeat clients. They illustrate that we really do offer the least expensive, lowest risk and fastest design capabilities available. We look forward to working with you.

Please Contact us for more information.



For any digital technology of the last 3 decades, "high speed " has usually referred to designing at close to the limit of a technology’s performance capability. Doing this job well involves rigorous timing analysis along with creative architecture design. In recent years, however, FPGA vendors, and to a lesser extent, ASIC vendors have begun to address speed bottlenecks with special features built into the device. Examples include on-chip block RAM, ROM, special-purpose interconnect, special purpose clock logic and clock routing, specialized IO circuitry, on-chip processor macros, and support for multiple IO standards. Using these features appropriately adds both more performance and more intelligent effort.

BLT considers the following issues for every design, but they are especially important where high performance in an FPGA or ASIC is imperative:
  • Employ synchronous design wherever possible.
  • Define multiple clock domains and interface between them correctly.
  • Evaluate candidate devices and pick the one appropriate to the task.
  • Identify high-speed areas of the design, which typically are a subset of the whole.
  • Allow adequate device resources, including routing, clock & memory resources.
  • Match critical device resources to the most demanding areas of the design.
  • Keep cost, schedule, and utilization tradeoffs in mind.
  • Establish timing constraints to constrain and verify timing of the entire device.
  • Consider early implementation and timing analysis for difficult parts of the design.
  • Be cognizant of the target clock rate(s) and “budget” the amount of combinatorial logic between register stages.
  • Analyze each interface to every external device and carefully choose IO architectures and signaling standards.
