Back in September, when I was just cutting my teeth on this EE Times EDA Designline thing, Synsopsys told me all about their brand new project called TLM Central. This is what I had to say back then:
TLM Central is a portal, repository and community for transaction-level models that will enable models that are available to be located by those who need them. I spoke with Tom De Schutter, senior product marketing manager, system level solutions within Synopsys. He explained that while this was a Synopsys effort, it was in no ways tied to Synopsys. They did considered going to the standards groups to get this effort going, but they decided it would be quicker to just fund it, develop it internally and get a critical mass of models into the repository (Over 600 for the release). Once it is running smoothly they would then consider finding a more permanent and independent home for it, but until then, they are committed to funding and maintaining the site.
Today, things have progressed quite a bit for them. They now have 840 models and Tom said that they have been happy with the uptake of the site by the commercial vendors, even though there is a lot more progress that can be made. They have also had success from the viewership side with over 4700 unique visitors to the site. Back when the site was introduced Tom had said “Synopsys also intends to work with Universities and to provide them with incentives to create models for more generic parts such as peripherals, DMAs etc. These would then be available in open source form so that people could modify them to fit their own specific needs.
” Now they are ready to take that step and are actually following through on their earlier plans.
The first change is that Synopsys has been putting some models on the site that can be downloaded for free. These are considered Open Source models and have a very simple user agreement that goes along with them, based on the Apache license. However, it enables users to download and make modifications to those models. Those modifications are owned by the user and there is no requirement that the modification be made public or uploaded onto the site. As Max would say – cool beans. While this is the first time that Synopsys has been public about these free models that they have donated, some of the models have already seen 30 downloads. The models that Synopsys has donated are things such as a battery model, UART and a generic memory model.
One community that would be a good source for models and a user of those models are the Universities and Synopsys is reaching out to them – with incentives. What would you do for an iPad2? In Tom’s latest TLMCentral blog
he talks about the new contest that they are running:
There are multiple ways to win
- Submit your model(s). An iPad2 winner will be drawn for the model developers contributing the first 50 models (any type of SystemC TLM-2.0 model). You get one entry per model you upload!Yes, it’s that simple!
- If you’re up for a bigger challenge, you can enter to win best model in the sensor device model competition.
- Upload the most models from a single participant by the end of March and win an iPad2!
- Get the highest vote out of any model loaded on TLMCentral by the end of April and win an iPad2!
- If your model has the most downloads by the end of May, win an iPad2!
One big push they want to make is with the sensor models and the deadline to get your entries in is Feb 17th – so you need to hurry on that one. Of course, the models have to be SystemC models that conform to TLM 2.0 so that the models are somewhat compatible with each other and can easily be used in a virtual prototype.Brian Bailey
