Michał Pietrusiński Applications aboot – command line utility to load Altera FPGAs interbs – simple command line utility to interact with JTAG boards Basic JTAG operations (TAP state, send/receive vectors of bits) Chip and board level operations – access to elements by its name: read/write specific chip registers execute JTAG instructions set/get state of specific pin/signal

Michał Pietrusiński Applications (cont’d) TTCcontr – Windows application that gives full control of TTCvi and TTCrx boards Supports older (TTCvi MK I) and latest (TTCvi MK II) versions of TTCvi Easy control of all TTCvi and TTCrx functions and settings User-defined sequences of B-Channel cycles stored in ini file Presettings (stored in ini file) - user can save current settings of TTCvi and TTCrx and apply theme later by clicking one button

Michał Pietrusiński Applications (cont’d) punit – visual Windows application to send test pulses using Pattern Unit (one word = 128 bits) edit scripts wtih signal definitions, macros, loops, etc. parse, programm device, run. tbcc (Test Bench Control Center) – visual application used to control RPC trigger prototypes during beam tests. Setting control registers. Histogramming

Michał Pietrusiński Beam-test software goals Hardware setup and control (FPGAs loading, setting control registers) Readout of boards, histogramming Intuitive GUI: software is to be used by non software experts Reusable, easy to modify High performance

Michał Pietrusiński II: VHDL and C++ VHDL and C++ code use common interface description files (iid) IID files describe: Registers, meanings of bits in registers, memory areas Their sizes Types of access IID files are directly included in C++ projects and automatically converted to VHDL using C++ preprocessor.
