Plunify – A Southeast Asian Giant Helping Business Build Better FPGA Products

The Silicon Review
February, 2020


Plunify makes life easier for users of FPGAs by removing barriers in the design process and saving valuable time as well as resources. Started in 2009 by two passionate engineers, Plunify focuses on optimizing chip design performance, starting with FPGA applications.

The ever-increasing complexities of FPGA devices and design flows bring new challenges every year. Harnessing increasingly-affordable compute resources, Plunify creates innovative solutions to optimize designs and accelerate product time-to-market.

Plunify’s first product was the EDAxtend platform, a cloud platform specifically designed to let engineers offload complex chip design builds. With cloud computing, data can be generated and analyzed cheaply. From machine learning-driven insights, Plunify created new products for FPGA design, such as the InTime software.

InTime is an expert software that optimizes FPGA design performance. Running on top of major FPGA tools, InTime delivers results quickly and enables higher productivity. It was the first commercial application of machine learning that enables chip design companies to significantly accelerate product Time-To-Market and reduce development costs.

Currently Plunify has operations in Singapore, Malaysia, China and Japan and counts Fortune Global 500 companies as clients.


A turnkey optimization service that gives results in days rather than weeks or months. This service is powered by InTime software, so there will be no RTL changes to the design.

This all-in-one service includes all the licenses required to run InTime and FPGA software, such as Vivado and Quartus. If you are facing a deadline, just provide them with an archive, checkpoint or snapshot of the design and they will deliver the required FMax or timing results.



InTime has built-in intelligence to predict optimized strategies for synthesis, placement and routing. It uses machine learning to actively learn from past results, improving the predictions over time. InTime can extract more than 50% increase in design performance from the FPGA tools.

Get to Timing Closure without RTL Changes

High resource utilization often leads to place-&-route timing issues. Or a 3rd-party IP that cannot be edited causes issues in the middle of a tight deadline. Sometimes it is just plain old “whack-a-mole” timing paths.

It is simply impractical to rip up and re-optimize the RTL all the time. Use InTime-optimized settings and constraints to achieve timing without changing RTL.

Reuse Results and Reduce Turnaround Time

Previous build results, good or bad, are valuable. From re-running previously generated settings to using incremental compilation, newer design revisions can benefit from older builds without going through the entire learning process again. Of course, the more builds InTime does, the higher the likelihood of a better result becomes.

Analyse & Troubleshoot Across Builds

InTime analytics help the client understand results and problems across multiple builds, instead of narrowly looking at a single build. From measuring logic vs. routing delays across “Common Critical Paths” (CCP) to “Errors and Warnings” analytics, the tool provides additional clarity on the design characteristics.

Faster Results over the Network

InTime works locally or on multiple computers in a network, distributing builds and aggregating results across machines automatically. It is integrated with resource management software like LSF or SGE. With Plunify Cloud, the client can offload builds to AWS without being a cloud expert.

FPGA-specific Optimizations

InTime supports major FPGA tools such as Quartus Prime, Vivado, and even ISE. Vendor- and architecture-specific optimizations are created for Xilinx and Intel.  These optimizations tackle different devices, design characteristics, floor planning and routing problems. Think of InTime as a personal support engineer.

Plunify Cloud Platform


Cloud computing reduces the need for upfront, possibly prohibitive fixed capital investment for a project. While it is simple to start one virtual server, orchestrating, managing and maintaining stable clusters of servers is much more complex.

Plunify Cloud is built for FPGA designers to easily utilize the power of cloud computing. It handles the complex technical and security aspects of managing a cloud infrastructure while simplifying access to it. With a suite of free Plunify cloud-enabled applications, any designer can quickly develop their FPGA projects on the cloud without having to be an IT expert.

Compute & Tools on Demand

Plunify Cloud sits inside the Amazon Web Services and handles the know-how for servers, storage, networking and most importantly, security.

With a wide range of server types available, starting an FPGA project in the cloud is just a few clicks away. Take advantage of on-demand compute power and tools to enable faster turnaround time, improve the cost-effectiveness of projects and explore new ways to solve timing problems.


HarnHua has more than a decade of experience in FPGA and embedded systems design at Xilinx, Inc. in San Jose, California and later on, in mobile computing platform development at Advanced Micro Devices (AMD) in Tokyo, Japan. He holds a Master’s Degree in Electrical Engineering from Stanford University and a Bachelor’s Degree in Electrical & Computer Engineering from Carnegie Mellon University, and is proficient in English, Mandarin and Japanese.
