Background to VHDL? Introduction to language? Using VHDL to synthesize and implement a design? Advantages: — — — — Documentation Flexibility easier to make design changes or mods Portability if HDL is standard One language for modeling, simulation test benches , and synthesis — Let synthesis worry about gate generation? Engineer productivity? However: A different way of approaching design — engineers are used to thinking and designing using graphics schematics instead of text.
Standard language used to describe digital hardware devices, systems and components — Developed initially for documentation?
Integration of std? A way of describing the operation of a system. Note: VHDL is case insensitive, free format. Comments are preceded by two consecutive dashes. PORTS are the communication links between entities or connections to the device pins? Consists of concurrent statements, e. There are many alternative ways to describe the required behavior of the final system — Exactly the same hardware will be produced — Some ways are more intuitive and easier to read? Spartan 3?
XC Series 3. Block RAM provides data storage — Kbit dual-port blocks? Multiplier blocks accepts two bit binary numbers? Each Virtex? Delay through the LUT is constant 0 0 0 0 0 0 0 0 1 1. Can be flip-flops or latches? Two in each slice; eight in each CLB? Input path — Two DDR registers? Separate clocks and clock enables for I and O? DCI provides — Output drivers that match the impedance of the traces — On-chip termination for receivers and transmitters?
Up to 3. True dual-port memory — Each port has synchronous read and write capability — Different clocks for each port? Supports initial values?
Synchronous reset on output latches? Optimized to implement multiply and accumulate functions? Multipliers are physically located next to block SelectRAM? A process which takes a digital circuit description and translates it into a gate level design, optimized for a particular implementation technology.
You will need to generate a file that the PROM programmer will understand — Directly from the computer? Summary: inferred 1 Decoder s. Strongly typed — more robust? Four-value logic system 0 — logic zero, or false condition 1 — logic 1, or true condition x, X — unknown logic value z, Z - high-impedance state?
Number formats b, B binary d, D decimal default h, H hexadecimal o, O octal? Uses subset of language for synthesis? Check - could you design circuit from description?
