Faster closure, simulation acceleration to emulation

It’s a longstanding cliché, but it is true that verification is a marathon. An integrated verification platform accompanied by a systematic verification methodology are the building blocks to manage the verification complexity of modern system-on-chip (SoC) designs. High performance simulation environment is the foundation however it is not enough to reach to the verification closure that requires regressing hardware in conjunction to real application scenarios and software.

MIPI SoundWire: Higher Bandwidth Through Bulk Register Access

MIPI SoundWire provides an optional mechanism for transporting register operations at higher bandwidth than mandatory command mechanism.  Bulk Register Access (BRA) protocol is a particular format of data transport to achieve the higher bandwidth.  While normal commands can only be driven at the rate of one command per frame, Bulk Register Access provides the option to read/write as many as 511 registers in one frame.  So a clock frequency of 5MHz and frame size of 256*16(4096 BitSlots or 2048 clock periods) will increase the effective rate of data transfer to approximately 1.2 MBps. MIPI SoundWire supports a frequency of up to 12 MHz, so the bandwidth can be even higher. In this blog I’ll focus on what a Bulk Register Access payload stream looks like and how it can be used to achieve higher bandwidth. BRA Payload Stream Since BRA is in no way related to actual audio transport we have the freedom to choose any values of word length and sample interval as per our needs. However, there are some restrictions as our aim is to transport a minimum of 11 bytes even in the worst case scenario (with 11 bytes we are only accessing 1 byte which is defeating the whole purpose of BRA, a normal command in this case would be more efficient). To use as many bits available in a frame for transporting data, sample word length can be set equal to hwidth and sample interval equal to number of columns. HStop can be set to max column and HStart to column 0 or 1 when lane 0 is being used.  Hence the specification recommends that Port 0 should support all values of word length from 1 to 16 as it provides the most efficient packing of data.

Verifying MIPI interfaces in SoCs

It is estimated that every smartphone now uses some aspect of the MIPI standards. Last year, one billion phones, and about 6 to 7 billion phone ICs, included a MIPI interface of some sort. MIPI interfaces, especially for cameras and displays, have spread beyond the mobile world into other markets, such as automotive, industrial, medical, the IoT and the digital home/office.

Benefits of MIPI Soundwire

In MIPI Soundwire: Digital Audio Simplified, we mentioned that digital audio formats, including Pulse Code Modulation (PCM) and Pulse Density Modulation (PDM), are target applications for MIPI Soundwire. Later, we discussed Digital Audio Streams and Channels. Here, we will talk about the merits MIPI Soundwire protocol has over other available digital audio interfaces.
