Hard IP for an embedded FPGA

Hard IP for an embedded FPGA
by Tom Dillinger on 04-30-2018 at 12:00 pm
Categories: Flex Logix, FPGA
1 Comment

As Moore’s Law enables increased integration, the diversity of functionality in SoC designs has grown. Design teams are seeking to utilize outside technical expertise in key functional areas, and to accelerate their productivity by re-using existing designs that others have developed. The Intellectual Property (IP) industry… Read More

The hierarchical architecture of an embedded FPGA

The hierarchical architecture of an embedded FPGA
by Tom Dillinger on 02-26-2018 at 7:00 am
Categories: Flex Logix, IP

The most powerful approach to managing the complexity of current SoC hardware is the identification of hierarchical instances with which to assemble the design. The development of the hierarchical design representation requires judicious assessment of the component definitions. The goals for clock distribution, power … Read More

"The Year of the eFPGA" 2017 Recap

"The Year of the eFPGA" 2017 Recap
by Tom Dillinger on 12-22-2017 at 7:00 am
Categories: Flex Logix, FPGA, IP

This past January, I had postulated that 2017 would be the “Year of the Embedded FPGA”, as a compelling IP offering for many SoC designs (link). As the year draws to a close, I thought it would be interesting to see how that prediction turned out.

The criteria that would be appropriate metrics include: increasing capital investment;… Read More

Image RemovedOne of the barriers to silicon success has always been design costs, especially if you are an emerging company or targeting an emerging market such as IoT. Today design start costs are dominated by IP which is paid at the start of the project and that is after costly IP evaluations and other IP verification and integration… Read More

Timing Analysis for Embedded FPGA’s

Timing Analysis for Embedded FPGA’s
by Tom Dillinger on 10-25-2017 at 7:00 am
Categories: Flex Logix, FPGA, IP
1 Comment

The initial project planning for an SoC design project faces a difficult engineering decision with regards to the “margin” that should be included as part of timing closure. For cell-based blocks, the delay calculation algorithms within the static timing analysis (STA) flow utilize various assumptions to replace… Read More

Embedded FPGA IP as a Post-Silicon Debugger

Embedded FPGA IP as a Post-Silicon Debugger
by Tom Dillinger on 09-08-2017 at 12:00 pm
Categories: Flex Logix, FPGA, IP

The hardware functionality of a complex SoC is difficult to verify. Embedded software developed for a complex, multi-core SoC is extremely difficult to verify. An RTOS may need to be ported and validated. Application software needs to be developed, and optimized for performance. Sophisticated methodologies are employed to… Read More

Embedded FPGA Blocks as Functional Accelerators (AMBA Architecture, with FREE Verilog Examples!)

Embedded FPGA Blocks as Functional Accelerators (AMBA Architecture, with FREE Verilog Examples!)
by Tom Dillinger on 07-20-2017 at 7:00 am
Categories: Flex Logix, FPGA, IP

A key application for embedded FPGA (eFPGA) technology is to provide functionality for specific algorithms — as the throughput of this implementation exceeds the equivalent code executing on a processor core, these SoC blocks are often referred to as accelerators. The programmability of eFPGA technology offers additional… Read More
