on what basis MMMC can be created? maximum how many corners a design can have?
Hi I have to implement multimode / multicorner in Magma for a particular unable to generate different timing reports after would be of great help to me if anyone could share abt this topic. Thanks inadvance
HI Do we need seperate sdc's for doing multimode multi corner sdc or we can merge sdc and run the P & R. Suppose we have funcitonal and Scan mode. And these modes are both operating at different frequencies. SO during optimization how tool decides (...)
MMMC - multi mode multi corner. Design need to close in different modes (Func mode, Test modes,TFT,ATPG ,MBIST etc). multi corner. In Lower technology nodes, design need to close with (...)
MMMC : multi mode : Differen modes. This can be functional,Test modes or any other modes. Inside functional mode, it can have many many modes like, PLL works at half frequency or works at high frequency. multi (...)
shahal, advanced STA questions will be more related to OCV (on chip variation ) , CPP ( common path pessimisim), how to calculate it...they will most likely draw a clk tree and a datapath , they will give you some values and will ask you to account for CPP and will ask you whether the given ckt meets timing or not ... there will be questions on
Is there any tutorial? Thanks very much.
hi, my 2 cents, what do you mean by timing convergence, is it timing corelation? * how to model wireload models and achieve better correlation and a faster timing convergence after p&r stage. * how to model the onchip variations and what are the various variations to account for and how much percentage to apply and achieve timing (...)
bc-wc takes in two libraries and does setup on wcs and hold on bcs. OVC uses just one library for setup/hold, but you can always load more corners in multi-corner analysis. bc-wc always uses slowest paths when doing setup checks. OCV can use fastest paths when doing setup checks, meaning it can speed up capture clock. (...)
Hi, looks like you have some confusion regarding the use of the scenario. As pavan mentioned that its combination of corner +mode, so first you have to understand what exactly it means... Its very difficult for me right now to capture all the points here.. ( I will do sometime in the weekend.. if you require).. but rig
MCMM is only multi corner & multi mode, that's means, you indicate to the tool, all the combination (rc-library) where you want the tool check the setup and the hold time. OCV (On Chip Variation), just add more timing varation over the design, for all the MCMM, it it generally apply after (...)
Hi, I need some clarification on multi voltage design. Lets say a particular instance in my design is running on two different voltages. In normal mode it runs on 1.2 volts and in special mode it runs on 0.8Volts. How is that done? I mean every cell in that instance will be linked to a library characterized by a (...)
HI, all~! I have question when trying to run post-layout simulation. the design is sign-off under MCMM ( multi-corner multi-mode ) For each scenario, we can generate a particular sdf by PrimeTime. There comes a question: Do we have to generate each sdf under different scenario ? (...)
Different high speed logic families can work at the GHz range. For example, current mode logic (CML) and dynamic logic. Actually, these two families are used for frequency dividers for PLLs working at multi-GHz frequency.
yes, you can. Power estimation tool takes netlist and power info for each gate from library. Gate level netlist does not depens on corner, but library is for specific corner. Just changing library, you can estimate power for different corners. It can be done in different sessions, or by using multi-scenario (...)
1. SDC : The tool will store below information in SDC . 1. Clocks and generated clocks. 2. Load and max slew values 3. Driving cell 4. IO delays. 5. Timing exceptions ( Max/Min delays, False paths and multi cycle paths). 2. The reason for bottom up synthesis , not to synthesize the hierarchical modules when you integrate the top level
