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