Great article by Tom De Schutter on using Physical Prototyping for software development. The article goes into other use cases and explores the age old make vs. buy decision making process.

This week Synopsys Introduced the DesignWare USB 3.1 Type-C IP with DisplayPort 1.3 and HDCP 2.2 for High-Bandwidth Data Transfer with Content Protection. USB has been continually evolving and USB Type-C is the one cable to connect them all. The USB Type-C is already gaining widespread acceptance and is becoming the most rapidly adopted USB standard in history. The need to rapidly adopt a new standard comes with challenges for the design engineers, verification team and the software developers.

Regardless of the market segment your product targets you are being required to build it with the lowest power operation to either compete, differentiate or just be more green. This week I ran into a customer who unfortunately had to re-spin their chip due to a low power mode of operation issue. The software was able to put the chip into a low power mode but due to a bug, they were unable to get the chip out of the low power mode cleanly without a system reset. This customer wanted to better verify the low power modes before tape-out this time around.
While traveling this week I found myself explaining the value of Hybrid Prototyping when used with DesignWare IP or your own IP blocks and RTL code. Simply put, using Hybrid Prototyping you can immerse the IP in the context of the SoC without needing to have RTL for the whole SoC. Hybrid Prototyping enables a Pre-RTL SoC representation to be rapidly created (using off the shelf Virtualizer Development kits as a starting point) and incorporating the block(s) under test modeled in HAPS Physical Prototype. This Hybrid Prototype is used for early software development in the case of the DesignWare IP and can be used in the same way for your own blocks in addition to increasing the verification of the design(s) under test.
A while back I wrote about a couple of ways to develop ARM-based software (and other CPU software) using either a physical connection to a hardware board with a CPU subsystem or a Virtual connection to a CPU subsystem using Hybrid Prototyping. I still stand by my conclusion that the Hybrid Prototyping approach provides the most flexibility and is the best solution for early software development.
I read an article recently which stated that emulation is the key to Virtual Prototypes, I would like to ride the theme wave and extend the horizon to include FPGA-based prototyping. Back in 2012, Synopsys introduced the first integrated Hybrid Prototyping solution, the combination of Virtualizer Virtual Prototypes and HAPS FPGA-based Prototypes. Our customers recognized a long time ago that the combination accelerates system bring-up by using virtual prototyping for new design blocks or CPU subsystems and FPGA-based prototyping for existing logic.
The term “Dark Fibre (Fiber) refers to the additional lines/capacity of optical connections a carrier would install when they laid a new pipeline. These unlit optical connections were built in assuming the need for additional capacity in the future. The thinking was that it’s cheaper to do it all at once vs. adding lines/pipelines later. The problem is that this extra capacity is going to waste and while the main carrier was not using it, someone else could have.
