Virtuoso Liberate MX Memory Characterization Solution Assignment Help


Range MX leverages innovation from Liberate MX to carry out “automated penetrating” and “vibrant partitioning” to resolve the runtime and precision obstacles that develop from analytical characterization of big macro obstructs that typically make up countless transistors. Given that a “vibrant partition” represents simply the active crucial course for an offered timing arc and is usually just a couple of hundred transistors, it can be identified utilizing comparable strategies as those released for analytical characterization of basic cells. This consists of defining the level of

sensitivity of both hold-up and timing restraints to worldwide (organized) and regional (random) procedure variations. Range MX has the ability to identify memory sizes that can not be effectively simulated utilizing brute Monte Carlo techniques and even with quick tasting strategies. Constructed on the leading Cadence ® Spectre simulation platform, Spectre XPS permits the simple re-use of designs, stimulus, analysis and general approach, therefore lowering assistance expenses while enhancing time to production. The combined Spectre simulation platform covers SPICE, advanced SPICE, RF and FastSPICE, allowing simple shift throughout analysis and streams; Spectre XPS incorporates into the Virtuoso ® Analog Design Environment for mixed-signal style, and into the Liberate MX memory characterization tool for SRAM memory characterization.

The faster throughput of Spectre XPS lets style groups carry out more precise and extensive simulations for big memory-intensive styles, in addition to low-power architectures that need higher exposure into parasitics. In addition to enhancements in throughput, the brand-new simulator needs 2 to 3 times less system memory than competitive offerings, enhancing calculate resources usage. The Cadence ® Virtuoso ® Liberate ™ MX memory characterization solution extends Cadence’s ultra-fast basic cell and I/O library characterization abilities to cover bigger macro blocks such as memory and customized cores. Macro obstructs need extra pre-analysis actions in order to make precise and quick characterization practical. The Liberate MX solution leverages a network of dispersed CPUs and uses the trademarked Inside View innovation for enhancing characterization runtime. In this method, cores and memories can be identified rapidly and quickly with the very same precision and techniques as basic cells, consisting of the generation of timing restraints and modeling of present source designs for timing and sound.

Application Notes

  • Spectre PSPICE Netlist Support

Spectre technologyenables the user to consist of PCB elements in PSPICE format into a Spectre incorporated circuit simulation. The solution is based upon the method of utilizing a routine Spectre simulation consisting of the Spectre simulator control declarations, however in addition permitting addition of user-defined sub-circuits in PSPICE format.

  • Establishing Liberate MX for Various Usage Models

This application note is meant to help you in comprehending the function and technique of Liberate MX and to assist you to pick the use design that finest fits the style that you are identifying.

  • Liberate MX: Debugging Netlist Issues

When establishing a circumstances that is to be defined utilizing Liberate MX, the user has to offer particular circuit details such as rails and bitcell. The characterization does not run properly if the user does not supply enough details about this. In this application note, we will go over the settings needed to define a circumstances and the best ways to identify if the needed details is missing out on.

  • Identifying Minimum Period and Minimum Pulse Width Using Liberate MX

The characterization of minimum duration and minimum pulse width arcs are among the most complex arcs in memory characterization. Each is comprised of numerous elements that should all be defined with the optimum worth being kept in the library file.

  • Utilizing and Debugging the Liberate MX Validation Flow

The Liberate MX recognition circulation makes it possible for the user to check the numbers in a library file by running a simulation with minimum worths for the promoted arcs. This is typically called an ‘at speed’ test. This test permits the user to confirm that the memory is practical with the timing numbers in the library file. Range MX utilizes “vibrant partitioning”, i.e. separating based upon a complete chip simulation of a circuit utilizing a “fast-spice” simulator. This has the benefit of having the ability to represent results typical at innovative procedure nodes such as adjoin coupling, power supply gating and transistor tension. As “vibrant partitions” are little, they can be identified by a “true-spice” simulator offering extremely precise outcomes. Without separating almost all memory circumstances are too big to be simulated with quick or conventional Monte Carlo techniques rendering analytical characterization difficult. To represent the effect of procedure variation Variety MX leverages Altos’ exclusive “within view” approaches that minimize the overhead of regional (random) variation characterization to 3X or less of small characterization, in contrast to Monte Carlo simulation which will be at least 2 or 3 orders of magnitude slower. The analytical library designs created by Variety MX follow those produced by Varietytm for basic cells. This consists of assistance for analytical existing source design formats, CCS VA from Synopsys and S-ECSM from Cadence.
