Efficiency Through Methodology
Efficiency Through MethodologyDVClub The document discusses methodologies for improving efficiency in verification testing at Cisco, including using reusable components from other projects, avoiding duplicate specifications, providing flexible testbenches, and automating tasks. It provides examples used at Cisco such as separating testbench creation into three stages, using testflow to synchronize component behavior, reusing unit-level checkers, linking transactions between checkers, and generating common infrastructure from templates to reduce designer effort. The biggest efficiency gains come from methodologies that push shared behavior into reusable components and standardize common elements.
Pre-Si Verification for Post-Si Validation
Pre-Si Verification for Post-Si ValidationDVClub 1) Pre-silicon verification is increasingly important for post-silicon validation as design complexity grows and schedules shrink. Bugs that escape pre-silicon verification can significantly impact post-silicon schedules and effort.
2) Mixed-signal effects, power-on/reset sequences, and design-for-testability features need to be verified pre-silicon to avoid difficult to reproduce bugs during post-silicon validation.
3) Case studies demonstrate how low investment in pre-silicon verification of areas like power-on/reset sequences and design-for-testability features can lead to longer post-silicon schedules due to unexpected bugs.

Provides hardware constructs and a simulation kernel for C++ It is a class library – And it is a language standard (IEEE 1666TM 2005) It has utilities and constructs – Data types, ports, channels, processes Adopted by different disciplines – Architectural Modeling (SoC, performance) – DV (RTL simulation, HW/SW co-verification) – Synthesis It is open source (OSCI) – http://www.systemc.org
- 5. DV Club, Boston Experiences with SystemC Why Avid Chose SystemC Enhanced existing C++ DV code – Replaced an unreliable in-house framework • Signal encapsulation • Thread management • Random seed management – Smooth transition from C++ to SystemC Tool availability – Single kernel multi-language simulator Industry acceptance Low cost Came with built-in verification capabilities
- 6. DV Club, Boston Experiences with SystemC Agenda What is SystemC? Why did Avid choose to use SystemC? DV problems solved by SystemC. Summary
- 7. DV Club, Boston Experiences with SystemC Crossing Language Boundaries Connect an entire HDL module to the testbench. – Wrap the module with a SystemC class (sc_foreign_module). – Provide a string mapping for each port. Connect a foreign signal anywhere in the hierarchy. – Bind a sc_signal (observe_foreign_signal). – Provide a string of hierarchical path to wire or reg.
- 8. DV Club, Boston Experiences with SystemC Code Examples SC_MODULE(MyVTB) { public: SC_CTOR(MyVTB) : MyDUTInst(“MyDUTInst”, “MyDUT”), MyMonitorInst(“MyMonitorInst”, “MyVTB.MyDUTInst.FooInst”) { MyDUTInst.reset(tb_reset); MyDUTInst.clock(tb_clock); MyDUTInst.AD(tb_AD); } private: MyDUT MyDUTInst; MyMonitor MyMonitorInst; sc_signal<sc_logic> tb_reset; sc_signal<sc_logic> tb_clock; sc_signal<sc_lv<16> > tb_AD; }; class MyDUT : public sc_foreign_module { public: sc_in<sc_logic> reset; sc_in<sc_logic> clock; sc_out<sc_lv<16> > AD; MyDUT(sc_module_nam nm, const char* hdl_name) : sc_foreign_module(nm, hdl_name), reset(“reset”), clock(“clock”), AD(“AD”){} }; class MyMonitor : public sc_module { public: MyMonitor(sc_module_name, const string& path2DUT){ string path2sig = path2DUT + “.snoop”; snoopSig_.observe_foreign_signal(path2sig); SC_THREAD(threadT); sensitive << snoopSig_.value_changed_event(); } private: sc_signal<sc_logic> snoopSig_; void threadT(); };
- 9. DV Club, Boston Experiences with SystemC Issues with Binding No clear standard for language boundary resolution. – Each vendor has its own implementation. – Implementation we use doesn’t map arrays or records (yet). Supporting foreign interface requires two pass compilation. – First pass creates object files. – Second pass builds a symbol library used in design elaboration.
- 10. DV Club, Boston Experiences with SystemC SystemC Connections Call a public method via pointer to object Connect sc_port to a sc_export Connect sc_port to a channel start()start() outp inp p p write() read()
- 11. DV Club, Boston Experiences with SystemC Code Examples struct start_stop_if : public sc_interface { virtual void start()=0; virtual void stop()=0; }; class MyBFM : public sc_module, public virtual start_stop_if { public: sc_in<sc_logic> Clock; sc_out<sc_logic> Request; sc_in<sc_lv<16> > AD; tlm::tlm_put_port<MyX> MyXReceivePort; sc_export<start_stop_if> StartStopExport; void start(); void stop(); SC_CTOR(MyBFM){ StartStopExport(*this); } }; SC_MODULE(MyTest){ public: sc_port<start_stop_if> bfm_port; }; SC_MODULE(vtb){ public: SC_CTOR(vtb); private: sc_signal<sc_logic> Clock; sc_signal<sc_logic> Request; sc_signal<sc_lv<16> > AD; tlm::tlm_fifo<MyX> MyXReceiveChan; MyTest MyTestInst; MyBFM MyBFMInst; }; vtb:vtb(sc_module_name) : MyBFMInst(“MyBFMInst”), MyTestInst(“MyTestInst”) { MyBFMInst.Clock(Clock); MyBFMInst.Request(Request); MyBFMInst.AD(AD); MyBFMInst.MyXReceivePort(MyXReceiveChan); MyTestInst.bfm_port(MyBFMInst.StartStopExport); }
- 12. DV Club, Boston Experiences with SystemC Issues with Connections Construction and binding are separate steps. – Ports must be public. – Ports bound after modules and channels are constructed. Binding uses “strict type checking”. – Compilation will fail if type mismatch in the connection. – Splitting a vector across multiple ports is complicated. Binding errors detected at elaboration. – Simulation should abort at runtime if a port is not bound. – Need to assign attributes to port (e.g. # of connections).
- 13. DV Club, Boston Experiences with SystemC Randomization Separate library dedicated to verification constructs (SCV). Robust, rich feature set for randomization. – Simple constraints (ranges and lists). – Complex constraint solver. – Thread-safe seeding. – Extendible to custom object types.
- 14. DV Club, Boston Experiences with SystemC Randomization at Avid SCV more than we needed. – So, we use a subset of the features. Provide a Tcl interface to apply constraints. – Wrap scv_smart_ptr. – Define string representations for simple constraints. – Recompilation not required to change constraints. – Reapply constraints over course of simulation.
- 15. DV Club, Boston Experiences with SystemC Processes Hardware is inherently parallel. DV must be multi-threaded. SystemC solves this with processes. – Macros: SC_THREAD and SC_METHOD. – Events, mutexes, semaphores. – Dynamic processes (sc_spawn).
- 16. DV Club, Boston Experiences with SystemC Hierarchy SystemC defines an object hierarchy. – Relates objects (parent/child). – Familiar to HDL design. Avid DV defines a layer hierarchy. – Relates connections. – Familiar to communication stacks. Issue: SystemC is not a methodology.
- 17. DV Club, Boston Experiences with SystemC Example Hierarchy VTOP VTEST VTB DUT Snooper_BFM Monitor Monitor Commander_BFM Driver Monitor TX_BFM Driver RX_BFM Monitor TLM Agent STIMGEN Translator Reference Model Analysis Agent Scoreboard Analysis Agent Test
- 18. DV Club, Boston Experiences with SystemC Agenda What is SystemC? Why did Avid choose to use SystemC? DV problems solved by SystemC. Summary
- 19. DV Club, Boston Experiences with SystemC Additional Issues Compile and link performance is disappointing. – Overuse of C++ templates in library. – Partially attributed to vendor implementation. Libraries are huge. Being a language standard has tool implications. C++ learning curve. – C++ code debug very different than HDL. • Segmentation faults, stack traces, code stepping Think like a HW engineer, code like a SW engineer.
- 20. DV Club, Boston Experiences with SystemC Avid’s Experience Used reliably for nearly 3 years. Runtime performance very satisfactory. Provides opportunity to assist product development beyond DV. – Evaluate architectures and predict performance. – Create programmer’s view models for emulation and HW/SW co-verification.
