Two years ago the photographer Palani Mohan received life-saving heart surgery. After his recovery he started to see the world and his work differently. He was drawn to images, old and new, that evoked silence and peace, and inspired reflection. ‘As we spend these days and weeks at home, I’m grateful for this time I have with my thoughts, and to witness the power of the small good things that surround us,’ he says. ‘My hope, especially in these difficult times, is that when you look at these images you can find a place for yourself within them, and be still.’

Modern systems-on-a-chip (SoCs) continue to increase in complexity, adding more components and calculation power to accommodate new performance-hungry applications such as machine learning and autonomous driving.  With increased number of SoC components, such as CPUs, GPUs, accelerators and I/O devices, comes increased demand to correctly model interoperability of various components. Traditional simulation of complex systems requires accurate models of all components comprising the system and normally results in very long simulation times. A better way is to create a set of typical traffic profiles which describe behavior of system’s masters and slaves. Such profiles should be abstract to be applied to various protocols and interfaces and be portable to be applied throughout different SoC design and verification cycles.

To address the challenges outlined above, Arm has recently announced availability of the AMBA® Adaptive Traffic Profiles (AMBA ATP) specification which lays foundation of a new synthetic traffic framework. The AMBA ATP specification includes detailed information of various transaction types and timing characteristics of those transactions. The traffic profiles defined in the specification are abstract in nature and thus could be used to generate stimuli for various standard AMBA protocols and in various environments such as RTL-based simulation, FPGA prototyping and final SoC verification. The traffic profiles outlined in the specification include a set of parameters to define timing relationships between transactions as well as timing relationships within individual transactions. Even though the traffic profile represents the behavior of a single agent it could be applied either in a concurrent manner (e.g. write and read traffic profiles running in parallel) or in a sequential manner (e.g. when one traffic completes before the next one start). Moreover, when simulating a reasonably complex system, it is possible to coordinate traffic profiles generated by multiple components. While providing abstract definition of traffic profiles, the AMBA ATP specification focuses on the use of traffic profiles with an AMBA AXI interface, outlining signaling, timing relationships between different transaction phases and between different transactions. The same application principles could be used to map the abstract traffic profiles to other AMBA protocols such as AMBA5 CHI protocol.  

To facilitate adoption of the AMBA Adaptive Traffic Profiles, Cadence has recently announced availability of SystemVerilog UVM ATP Sequence Layer which automatically implements mapping of an abstract ATP traffic to AMBA protocol specific traffic, generated by Cadence AMBA Verification IP. The ATP layer is implemented as a SystemVerilog UVM virtual sequence with the sequence item including all ATP transaction parameters as defined in the specification.

Using the provided sequence infrastructure, users can write tests to define and coordinate traffic profiles for various components in the system. The ATP Layer automatically converts the abstract traffic profile into AMBA protocol-specific traffic, e.g., AMBA5 CHI protocol traffic.

 A sample code below, shows an example of a read profile translated by Cadence ACE Verification IP in ACE protocol traffic.

                        ace_atp_vseq.addressPattern == ATP_SEQUENTIAL;  // address pattern

                        ace_atp_vseq.transactionSize == 64;                             // number of bytes in each burst

                        ace_atp_vseq.dataSize == 4;                                          // number of bytes in each transfer

                        ace_atp_vseq.rate == 150.0/(50.0);                                // requestedBandwidth / clkFrequency

                        ace_atp_vseq.start == ATP_EMPTY;                              // start condition of the ATP FIFO

                        ace_atp_vseq.full == 128;                                               // full level of the ATP FIFO

                        ace_atp_vseq.numOfTransactions == 500;                    // number of bursts issued by this sequence

                        ace_atp_vseq.ARTV == 2;                                              // sub-transaction delay

                        ace_atp_vseq.RBR == 3;                                                // sub-transaction delay

There has been so much hype about the “Internet of Things” (IoT) that it is refreshing to hear about a cutting-edge development project that can bring concrete benefits to millions of people. That project is the ongoing development of the Google Smart Contact Lens, and it was detailed in a keynote speech June 8 at the Design Automation Conference (DAC 2015).

The keynote speech was given by Brian Otis (right), a director at Google and a research associate professor at the University of Washington. The “smart lens” that the project envisions is essentially a disposable contact lens that fits on an eye and continuously monitors blood glucose levels. This is valuable information for anyone who has, or may someday have, diabetes.

Since he was speaking to an engineering audience, Otis focused on the challenges behind building such a device, and described some of the strategies taken by Google and its partner, Novartis. The project required new approaches to miniaturization, low-power design, and connectivity, as well as a comfortable and reliable silicon-to-human interface. Otis discussed the “why” as well and showed how the device could potentially save or improve millions of lives.

Millions of Users

First, a bit of background. Google announced the smart lens project in a blog post in January 2014. Since then it has been featured in news outlets including Forbes, Time, and the Wall Street Journal. In March 2015, Time reported that Google has been granted a patent for a smart contact lens.

The smart lens monitors the level of blood glucose by looking at its concentration in tears. The lens includes a wireless system on chip (SoC) and a miniaturized glucose sensor. A tiny pinhole in the lens allows tear fluid to seep into the sensor, and a wireless antenna handles communications to the wireless devices.

“We figure that if we can solve a huge problem, it is probably worth doing,” Otis said. “Diabetes is one example.” He noted 382 million people worldwide have diabetes today, and that 35% of the U.S. population may be pre-diabetic. Today, diabetics must *** their fingers to test blood glucose levels, a procedure that is invasive, painful, and subject to infrequent monitoring.

According to Otis, the smart contact lens represents a “new category of wearable devices that are comfortable, inexpensive, and empowering.” The lens does sensor data logging and uses a portable instrument to measure glucose levels. It is thin, cheap, and disposable, he said.

Moreover, the lens is not just for people already diagnosed with diabetes—it’s for anyone who is pre-diabetic, or may be at risk due to genetic predisposition. “If we are pro-active rather than re-active,” Otis said, “Instead of waiting until a person has full-fledged diabetes, we could make a huge difference in peoples’ lives and lower the costs of treating them.”

Technical Challenges

No one has built anything quite like the smart lens, so researchers at Google and Novartis are treading new ground. Otis identified three key challenges:

• Miniaturization: Everything must be really small—the SoC, the passive components, the power supply. Components must be flexible and cheap, and support thin-film integration.
• Platform: Google has developed a reusable platform that includes tiny, always-on wireless sensors, ultra low-power components, and standards-based interfaces.
• Data: Researchers are looking for the best ways to get the resulting data into a mobile device and onto the cloud.

Comfort is another concern. “This is not intended to be for the most severe cases,” Otis said. “This is intended to be for all of us as a pro-active way of improving our lifestyles.”

The platform provides a bidirectional encrypted wireless link, integrated power management, on-chip memory, standards-based RFID link, flexible sensor interface, high-resolution potentiostat sensor, and decoupling capacitors. Most of these capabilities are provided by the standard CMOS SoC, which is a couple hundred microns on a side and only “tens of microns” thick.

Otis noted that unpackaged ICs are typically 250 microns thick when they come back from the foundry. Thus, post-processing is needed so the IC will fit into a contact lens.

Furthermore, the design requires precision analog circuitry and additional environmental sensors. “Some of this stuff sounds mundane but it is really hard, especially when you find out you can’t throw large decoupling capacitors and bypass capacitors onto a board, and all that has to be re-integrated into the chip,” Otis said.

Sensor Challenges

Getting information from the human body is challenging. The smart lens sensor does a direct chemical measurement on the surface of the eye. The sensor is designed to work with very low glucose concentrations. This is because the concentration of glucose in tears is an order of magnitude lower than it is in blood.

In brief, the sensor has two parallel plates that are coated with an enzyme that converts glucose into hydrogen peroxide, which flows around the electrodes of the sensor. This is actually a fairly standard way of doing glucose monitoring. However, the smart lens sensor has two electrodes compared to the typical three.

In manufacturing, it is essential to keep costs low. Otis outlined a three-step manufacturing process:

• Start with the bottom layer, and mold a contact lens in the way you typically would.
• Add the electronics package on top of that layer.
• Build a second layer that encapsulates the electronics and provides the curvature needed for comfort and vision correction.

Beyond the technical challenges are the “clinical” challenges of working with human beings. The human body “is messy and very variable,” Otis said. This variability affects sensor performance and calibration, RF/electro-magnetic performance, system reliability, and comfort.

The final step is making use of the data. “We need to get the data from the device into a phone, and then display it so users can visualize the data,” Otis said. This provides “actionable feedback” to the person who needs it. Eventually, the data will need to be stored in the cloud.

As he concluded his talk, Otis noted that the platform his group developed may have many applications beyond glucose monitoring. “There is a lot you can do with a bunch of logic and sensing capability,” he said, “and there are hundreds of biomarkers beyond glucose.” Clearly this will be an interesting technology to watch.

For a netlist vs. netlist LEC flow we have to solve the following problem:

- in the RTL code we replicate a large array of N x M all-identical hard-macros, let call them MACRO_A

- MACRO_A is pre-assembled in Innovus and contains digital parts and analog parts (bottom-up hierarchical flow)

- at top-level (full-chip) we instantiate this array of all-identical macros

- in the top-level place-and-route flow we perform ecoChangeCell to remaster the top row of this array with MACRO_B

- MACRO_B is just a copy of the original MACRO_A cell containing same pins position, same internal digital functionality and also same digital layout, only slight differences in one analog block inside the macro

- MACRO_A and MACRO_B have the same .lib file generated with the do_extract_model command at the end of the Innovus flow, they only differ in the name of the macro

- when performing post-synthesis netlist vs post-place-and-route we load .lib files of both macros in Conformal LEC

- the LEC flow fails because Conformal LEC sees only MACRO_A instantiated in the post-synthesis netlist and both MACRO_A and MACRO_B in the post-palce-and-route netlist

Since both digital functionality and STD cells layout are the same between MACRO_A and MACRO_B we don't want to keep track of this difference already at RTL stage, we just want to perform this ECO change in place-and-route and force Conformal to assume equivalence between MACRO_A and MACRO_B .

Basically what I'm searching for is something similar to the add_instance_equivalences Conformal command but that works between Golden and Revised designs on cell primitives/black-boxes .

Is this flow supported ?

Thanks in advance

Hello, i have a realy mistick thing going with copying libraries in cadence virtuoso,

When i copy straight forwart the whole library it gives me a warning that accsess was denied,but when i go into the library and copy it as a single file, then it goes fine.

another problem is it doesnt show in the massage console  ALL the files which could not be copied.(which is the much bigger problem,becuase i would have to pass threw all the subdirectories to verify if all files are there)

Is there a way to see which files wasnt able to be copied?

Hello, i am a student who is studying Allegro tool with SKILL.

I have a question about SKILL axlSegDelayAndZ0. The reference says this function "returns the delay and impedance of a cline segment."

I want to know how many components does this tool consider when calculating timing delay from the length. 

How steep is input signal's rise transition? Is rise transition shape isosceles trapezoid or differential increasing shape?

Also, if it is a multi fan-out, the rise transition time will be different net by net. How can this tool can calculate in this case?

I want to hear answers about these questions.

Thank you for reading this long boring questions, and i will be waiting for answers.
