VSD - Embedded-UVM
What you'll learn
- We take a dive into Embedded UVM and its use cases as a platform for Functional Verification and SoC FPGA based Emulation
- We learn how to code Embedded UVM powered testbench for a hardware accelerator design IP
- The test bench is then adapted to Cyclone V and Ultrascale Zynq based platforms to demonstrate Embedded UVM powered low-cost SoCFPGA based emulation solutions.
- Basics of UVM is nice to have
- Basics of digital design is a must to have
- Novice knowledge of opensource EDA flow is nice to have
Of course, there is a requirement for open-source verification, but that’s not the only thing we want to cater to. There are other verification trends and challenges which system Verilog and other verification platforms are not able to meet. So, we want to position Embedded-UVM for that. In the past decade or so, the major thing which is making verification tougher than it used to be, is the death of Moore’s law.
As far as processor frequency goes, it stabilizes at 4GHz and it's coming down as we move to multi-core processors. So, when you look at it from a simulation perspective, post-2005 it is becoming increasingly difficult to run simulations on bigger chips.
Chip size keeps increasing, while processor speed is stagnant and hence, simulation is a limiting factor. Simulation speed is going to be limited unless we move to multi-core processors. Contemporary EDA tools run RTL simulations in a multi-core environment. System Verilog doesn’t run in a multi-core environment.
Therefore, test-bench runs on one thread and RTL runs on multiple threads. RTL is more formal in nature, in sense, it can be synthesized, it can be partitioned, different partitions can run on different processors, while test-bench is behavioral in nature and it cannot be partitioned the way RTL can be.

Hands on with Technology @
1) MSM (mobile station mode chips) - MSM chips are used for CDMA modulation/demodulation. It consists of DSP’s and microprocessors for running applications such as web-browsing, video conferencing, multimedia services, etc.
2) Memory test chips - Memory test chips are used to validate functionality of 28nm custom/compiler memory as well as characterize their timing, power and yield.
3) DDR-PHY test chips - DDR-PHY test chips are basically tested for high speed data transfer
4) Timing and physical design Flow development for 130nm MOSFET technology node till 16nm FinFET technology node.
5) “IR aware STA” and “Low power STA”
6) Analyzed STA engine behavior for design size up to 850 million instance count ACADEMIC
1) Research Assistant to Prof. Richard Pinto and Prof. Anil Kottantharayil on “Sub-100nm optimization using Electron Beam Lithography”, which intended to optimize RAITH-150TWO Electron Beam Lithography tool and the process conditions to attain minimum resolution, use the mix-and-match capabilities of the tool for sub-100nm MOSFET fabrication and generate mask plates for feature sizes above 500nm.
2) Research Assistant to with Prof. Madhav Desai, to characterize RTL, generated from C-to-RTL AHIR compiler, in terms of power, performance and area. This was done by passing RTL, generated from AHIR compiler, through standard ASIC tool chain like synthesis and place & route. The resulting netlist out of PNR was characterized using standard software
1) “A C-to-RTL Flow as an Energy Efficient Alternative to Embedded Processors in Digital Systems” submitted in the conference “13th Euromicro Conference on Digital System Design, Architectures, Methods and Tools, DSD 2010, 1-3 September 2010, Lille, France”
2) Concurrent + Distributed MMMC STA for 'N' views
3) Signoff Timing and Leakage Optimization On 18M Instance Count Design With 8000 Clocks and Replicated Modules Using Master Clone Methodology With EDI Cockpit
4) Placement-aware ECO Methodology - No Slacking on Slack
Tips on order in which you need to learn VLSI and become a CHAMPION:
If I would had been you, I would had started with Physical Design and Physical design webinar course where I understand the entire flow first, then would have moved to CTS-1 and CTS-2 to look into details of how the clock is been built.
Then, as you all know how crosstalk impacts functioning at lower nodes, I would gone for Signal Integrity course to understand impacts of scaling and fix them. Once I do that, I would want to know how to analyze performance of my design and I would have gone for STA-1, STA-2 and Timing ECO webinar courses, respectively
Once you STA, there’s an internal curiosity which rises, and wants us to understand, what goes inside timing analysis at transistor level. To full-fill that, I would had taken Circuit design and SPICE simulations Part 1 and Part 2 courses.
And finally, to understand pre-placed cells, IP’s and STA in even more detail, I would have taken custom layout course and Library Characterization course
All of above needs to be implemented using a CAD tool and needs to be done faster, for which I would have written TCL or perl scripts. So for that, I would start to learn TCL-Part1 and TCL-Part2 courses, at very beginning or in middle
Finally, if I want to learn RTL and synthesis, from specifications to layout, RISC-V ISA course will teach the best way to define specs for a complex system like microprocessor
