Next, we run Spyglass Power, using the simulation vectors. We wrote a C program to compile these individual power estimates, taking in account their duration, to create a spyglass scorecard for the CPU. It’s uwer of our mainstream design flow, and all the evidence is that Spyglass Power will meet the needs of our new designs, which will be up to 2. We are happy with Spyglass. Our architects use Spyglass at the architectural level as follows: Power figures for guid modules There is a feature of Spyglass Power which gives you a graph of usef activity in the design, allowing us to see the activity is for a particular block, even without actually doing any power computations.
Our typical projects tend to run months. Spyglass’ design flow integration allows our designers to focus on the results of the tool: Spylgass register file was our greediest module. I would like to also thank Ahmed Jerraya and Erwan Piriou, who cooperated with me on this eval.
We’ve run atrenta spyglass user guide lot of correlations to assess for Spyglass’ power estimation accuracy. Atrenta spyglass user guide said here is just one engineer’s opinion. Suffice to say, that is absolutely precise enough to make design decisions for power reduction. Power graph for architecture This was a situation where the Atrenta spyglass user guide Power activity report showed that a cluster of the design that should have been in an idle state was atrenta spyglass user guide and drawing power when it shouldn’t have been.
Using Atrenta Spyglass in GUI Mode_图文_百度文库
At my company we have 2 primary types of Spyglass users: Spyglass has no problems with mixed language support. Ayrenta we run simulation vectors to functionally verify our design; we mostly design in VHDL, with some Verilog.
Typically, this second stage includes optimizations focused on applying specific sequential and formal techniques to reduce register and memory power. We are looking at new design optimization techniques using the substrate, based on substrate polarization that changes, atrenta spyglass user guide example, the transistor power consumption and speed.
This was useful for power planning at SoC level during early design development phase SoC power architecture specification. The architect atrenta spyglass user guide runs Spyglass Power to find power bugs.
However, for detailed power optimization during the RTL design phase, we need simulation vectors to get sufficient accuracy.
We intend, in the coming weeks, to use Spyglass Power for defining using its power estimation feature the right set of operating points voltage, frequency for our Atrenta spyglass user guide Voltage and Frequency Scaling. Spyglass’ sequential analysis and equivalence checking lets us test this.
Spyglass Power for both architectural and RTL power reduction
For every instruction and couple of instructions, we generated atrenta spyglass user guide simulation vectors. So far, we haven’t seen any serious problems. The memory power reduction comes from rules such as: We came up with a clever way to use Spyglass to create a power model to analyze power consumption and optimize our programmable core design at the architectural level.
These are highly skilled designers who usually assume that a tool cannot aternta better than they can! The other primary users of Spyglass power are our experts in low-power design. If we do not have simulation vectors, then Spyglass can work with default activity parameters to provide rough estimation. This opportunity to consider programmable architectures in terms of power consumption especially makes sense for compiler and hardware designers looking atrdnta power saving.
This is a discussion. Sign up for the DeepChip newsletter. The architect removed these power bugs by manually adding clock- gating cells at the cluster-level. We can extract a lot of different reports atrennta Spyglass, such as what is clocked and what atrenta spyglass user guide not clocked; this helps to guide us in atrenta spyglass user guide micro-architecture.
We input simulation vectors to Spyglass, to get power estimates. Read what EDA tool users really think.
atrenta spyglass user guide Email in your dissenting letter and it’ll be published, too. We work on advanced design technologies with industrial partners such as ST Microelectronics. Spyglass Power looked at every single register and memory inside the block — gide can be 10,’s of them — to see if it could gate them.
The tool is stable and we get same-day support. We use it, it works.
We have recently used Spyglass on two different chips; below I have 4 sample case studies of our power spyglas results.
We are a silicon conductor research institute. Our two main applications today are advanced telecom basebands and multi-processor SoC’s for computing.
Atrenta spyglass user guide initial power reduction done by one of our best local designers. I would estimate we’ve had a 2 months savings with it.
Attrenta then did final analysis for clock-gating. Our architect uses our internal RTL generator to generate RTL code with a reconfigurable clusterized architecture; without doing any clock gating yet.
