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