© 2000 Altera Corporation 8 Design Methodologies Quartus supports three common design methodologies: –Top-down Create a top-level of the design first, and then break down the design into lower-level design blocks. –Bottom-up Begin by creating the lower-level design blocks first and then stitch together the design at the top-level. –Middle-out Start in-between Top-down and Bottom-up design methodologies

© 2000 Altera Corporation 9 Design Entry Multiple design entry methods –Quartus Block/Schematic Editor Text Editor –AHDL, VHDL, Verilog Memory Editor –Hex, Mif –Third party EDA tools EDIF HDL VQM –Add flexibility and optimization to the design entry process by: Mixing and matching design files Using LPM and Megafunctions to accelerate design entry

© 2000 Altera Corporation 53 Introduction to Quartus Design Flows Quartus allows for three possible design flows : –Quartus Driven Flow: User launches other EDA tools from Quartus No need to learn 3rd party EDA tool –Vendor Driven Flow: User runs Quartus in the background from the 3rd party EDA tools –File Based Flow: Very little integration between Quartus and 3rd party EDA tools

© 2000 Altera Corporation 54 Quartus Driven Flow –EDA tools launched from within Quartus –Code level integration Cross probing and error location –Quartus automatically generates the netlists or reads in the netlists based on the tool –User doesn’t have to learn the setup and the flow Synthesis Tool Tcl COM (C++, VBScript) API Cross Probe Error Locate Quartus drives the third party EDA software

© 2000 Altera Corporation 55 Vendor Driven Flow –Offers the tightest code-level integration between tools –Quartus appears ‘Native’ in third party EDA software Third party EDA software drives Quartus Synthesis Tool Tcl COM (C++, VBScript) Cross Probe Error Locate API

© 2000 Altera Corporation 56 NativeLink Features Minimizes designer interaction with different EDA tools –Allows designers to complete their designs using as little as one tool Cross-referencing –Nodes from place-and-route result can be traced back to HDL code across from Quartus to a synthesis tool Improved Quality of Results (QoR) –Nativelink lets synthesis tools map directly into the fundamental building block of an architecture Iterative Compile –Improves QoR from synthesis tools –Allows Quartus to pass routing delay information after place-and- route back to the synthesis tools –Synthesis tools can then re-synthesize the design based on the feedback

© 2000 Altera Corporation 57 Quartus NativeLink interface is comprised of two components: –External Files: WYSIWYG (What You See Is What You Get) ATOM netlist files (EDIF, Verilog, VHDL) cross reference files (ex. xrf), timing files (ex. sdo) etc. –Application Programming Interface (API) Functions - a pre- defined interface EDA Partners API External Files NativeLink Quartus

© 2000 Altera Corporation 58 WYSIWYG ATOM Primitives A set of design primitives that support WYSIWYG compilation Provides direct control of how a design is technology mapped to a specific target device Helps synthesis vendors provide an optimal realization of a design for a device architecture WYSIWYG elements in the design are translated as directly as possible for fitting and routing purposes
