• Create top-level testbench:– Used as a simulation framework for the different tests. Testbench instantiates
the DUT (FPGA or module), instantiates all BFMs (memory models, ICs, processors, etc) makes all interconnections and generates the clocks, resets and other board signals.
– Testbench also provides some useful tasks, for example to read input files, read/write buffers to external memory, simulate registers accesses, etc.
• Creation of additional test benches: – Top test bench as a framework. This test bench is actually a program that
contains calls to the framework tasks and probably new tasks or code specific for this test.
– Reduces duplicated efforts, allows for changes to BFMs or clock speeds and automatically updates all test benches (since only the top test bench is modified) and guarantees that everyone is using the same setup.

• Created a common core of tests written in TCL that can be used in a variety of ways both for physical hardware verification and simulation modeling
• System is mixed signal IC tester with PCIe communication through backplane to PC running a control application
• Spartan 6 contains PCIe soft core
www.A2eTechnologies.com
Example: Tcl Scripts for Spartan 6 - PCIeExample: Tcl Scripts for Spartan 6 - PCIe
• PC Application : Run Tcl on PC to connect as a normal test application. – Uses the same calls as PC drivers and (undocumented API) application code would use. This runs the
core scripts against real hardware in real-time. A full diagnostic takes 20 seconds to run.• JTAG Intervention: Connect a JTAG cable to a laptop running the JTAG Tcl script.
– This connects the TCL core against the FPGA directly (no PCIe required) through the JTAG port. – Allows verification of register settings after complicated software operations are completed and without
altering those software applications. – Can also take direct control of UPU64 hardware if testing requires this.
• Fast simulation: Run TCL scripts from the Modelsim (a VHDL/Verilog) simulator command line. – The core library turns complex commands (e.g. write a block of data to the non-volatile memory) into
simple commands that are passed to the Fast simulation shim which directly forces a simple 32-bit bus within the FPGA model (in VHDL and Verilog) and conducts transactions.
• PCIe simulation: – Use the TCL core library in Modelsim with a shim to connect to the FPGA through a virtual host side PCIe
transaction. – In simulation, this enumerates the PCIe bus at startup, allocates resources and allows all PCIe
transactions to be fully simulated.
