Verification Automation Solutions for Arm AMBA Coherent Interconnects

Arm TechCon 2017 took place at Santa Clara on 24-26th Oct, 2017. This year, Synopsys’ Arm® AMBA® protocol experts were on hand to demonstrate our verification automation solutions for Arm AMBA Coherent Interconnects. Synopsys Auto SoC Testbench generation solution enables easy and quick integration and configuration of hundreds of coherent and non-coherent AMBA ports and corresponding VIP instances. Our experts also introduced our AMBA AutoPerformance solution to generate AMBA(CHI/ACE/AXI) interconnect performance verification stimulus. The AutoPerformance solution, based on Arm traffic profile specification, enables user to define traffic profiles for measurement of performance metrics like throughput, latency etc., and the stimulus is driven by VIP for AMBA (CHI/ACE/AXI).

LPDDR4: The Total Package for Mobile SoC RAM

The mobile industry is growing at a very fast pace with its never-ending hunger for data and bandwidth. We have witnessed the change from a dial-pad to touch-screens, from black and white display to QHD 4k display with millions of colors, and memory space from KB to GB, in a very short span of time. The biggest challenge is increasing bandwidth without compromising performance or adding any significant numbers in the power consumption column. The solution to this challenge is the LPDDR or Mobile DDR standard released by JEDEC. There have been several revisions to this standard, the latest being LPDDR4. LPDDR4 provides a data bandwidth of 4266 Mbps, which is almost double that of LPDDR3. It also provides a significant reduction in power consumption compared to LPDDR3. For further insights on LPDDR4 and its predecessors please refer to our previous blog “LPDDR4: What Makes it Faster and Reduces Power Consumption.”

LPDDR4: What Makes It Faster and Reduces Power Consumption

DRAM memories are the ‘heart’ of any computational device, e.g. smart phones, laptops, servers etc. LPDDR4 was mainly designed to increase memory speed and efficiency for mobile computing devices such as smartphones, tablets, and ultra-thin notebooks.  It supports speeds up to 4267Mbps (double the speed of LPDDR3) and 1.1 V input/output buffer power, along with many other improvements compared to its predecessor (LPDDR3/LPDDR2). Below is a comparison of key features between all the three generations of LPDDR.

Jumping the Barrier of Verifying Arm AMBA ACE Protocol Barrier Transactions

The ordering of memory transactions in Arm® AMBA® protocol is a significant requirement, i.e. the sequence of memory updates/accesses must follow a defined ordering as per the specification. Ordering is important for synchronization events by a processor with respect to retiring load/store instructions. AMBA ACE barrier transactions are used for maintaining the memory ordering across a system. The learning curve to understand barrier transactions may become a barrier to verify your design thoroughly. This blog provides insight, making it easier to understand and verify the barrier transactions. The blog will cover different types of barrier transactions, usage, and domain boundaries.
