Flex Logix, the eFPGA licensing  specialist, has qualified several Serial I/O IP cores from CAST and SOC Solutions for use in its EFLX Embedded FPGA.

Flex Logix eliminates the need for customers to write their serial I/O code from scratch. Details including LUT counts and frequencies for specific processes are available in a Flex Logic Reconfigurable Serial IO application note.

A common use of EFLX Embedded FPGA is as a customisable I/O block that allows serial I/O to be programmable rather than hard-wired in MCUs, IoT, and SoC applications.

Today, an IC company either has to do many mask versions — each needing qualification — or it fails to meet the needs of all customers and loses potential business.
Each end application has varying serial I/O requirements, and having EFLX embedded FPGA supported with pre-qualified serial I/O IP gives semiconductor companies flexibility in supporting those requirements with confidence.

“We engaged with CAST and SoC solutions beccause they are the best IP suppliers,” says Flex Logix CEO Geoff state, “and we have already run their cores through our software to determine LUT counts and frequencies in 40nm. We appreciate the technical support and cooperation of CAST and SoC Solutions, and are pleased to offer our customers two qualified sources of Serial I/O IP.”

Flex Logix’s customers to date are primarily IC companies and the large systems companies that design their own ICs. In most cases, they have their own RTL IP such as Verilog and VHDL code for implementing key functions. But in some cases, they are interested in acquiring RTL IP.

The I2C and SPI bus controlers and UART cores are part of the line of digital IP cores and subsystems offered by CAST, which includes processors, video and data compression, peripherals, interfaces, and more. See www.cast-inc.com for technical and sales information. Several of these cores are sourced SoC Solutions.
EFLX is a digital architecture for integrating FPGAs into SoCs, ASICs and MCUs. The EFLX arrays are programmed using VHDL or Verilog, and the EFLX compiler takes the output of a synthesis tool such as Synopsys Synplify and does packing, placement, routing, timing and bitstream generation. The bitstream, when loaded into the array, programs it to execute the desired RTL.

EFLX embedded FPGAs are available now in 40nm, 28nm and 16nm process nodes and Flex Logix is responding to customer requests for other process nodes. Over time, EFLX will be available on all of the popular process nodes from 180nm to 7nm.
