  2. IP library -development and management What is required for an IP Library: • Documentation! Documentation! Documentation! • EDA library database • Common standard for designing of IP blocks • Core supported tools set • Acceptance criteria and peer review • Revision control • Storage and access

  3. EDA library database EDA library database should contain: • Description of block and it’s function • Specification of IP across PVT corners • Design database cell views and textual files • Layout pinout/placement details (Hardblocks) • Test benches to simulate/verify • Synthesis/P&R scripts (Softblocks) • Datasheets (Waveforms/measurements)

  4. EDA library database-analogue focused • Block cell views: schematic/layout/symbol/verilog(a/ams)/config/abstract • Test benches used to characterised IP block • Multi-testbench simulation environment: adexl • Datasheet with simulation results automatically generated from ADEXL • Files • Liberty black box model(pin info/antenna) • Verilog model(black box) • Spice subcircuit (Pre/post-layout) for fast spice modelling • LEF file for standalone P&R environment • GDSII and layers file

  5. IP library structure Open Access IPLibrary Cell level IP_BlockTB_AC IP_BlockTB_TRAN .. IP_Block View level schematic schematic schematic constraints config config verilogA/AMS configPS .. symbol configAMS layout config= netlist view list control configPS=netlist for post layout configAMS= netlist for simulator extracted ADEXL Refs testbenches State files

  6. Parameters for Circuit Opt. ADEXL view Corners set for PVT Multi-test env. Auto. gen. datasheets Documentation ADEXL Specifications State files Yield analysis

  7. Conclusions ADE XL/GXL provides: • Central location for storing simulation results and documentation • Automatic generation of datasheets • Specification driven environment • Platform for retargeting/optimisation IP blocks
