System Generator

Purpose & User Intent: This tool models System Generator workflows to estimate resource usage, timing feasibility, and configuration impacts for FPGA designs. Target users are FPGA design engineers, verification teams, and project managers evaluating HDL-based implementations before detailed synthesis. When early feasibility is needed, this tool provides rapid guidance on architecture choices and constraints.
Core Logic & Features: The system applies domain-specific rules to map high-level design parameters to resource estimates (LUTs, FFs, BRAM, DSP slices) and timing implications. Required features include input validation of FPGA family, clock, data widths, throughput, and latency targets; resource and timing estimation; constraint-checking and feasibility warnings. Optional/advanced features include parameter sweeps, sensitivity analysis, and export-ready summaries.
Inputs & Outputs: Inputs (name, type, units, sample values, validation, required/optional): target_fpga (string, e.g., "Kintex UltraScale"), clock_frequency_mhz (number), data_path_width (integer, bits), throughput_mpps (number), latency_constraint_ns (number, optional), use_dsp_blocks (boolean, optional, default true), enable_pipelining (boolean, optional). Outputs: resource_estimates (LUTs, FFs, BRAM_18k, DSPs), timing_margin_ns, recommended_config (string), feasibility_flag (boolean).
Algorithms & Calculations: Applies heuristic mappings from input parameters to known architectural blocks; uses conservative margins for uncertainty; supports simple block-level estimation and optional detailed mode for DSP- or BRAM-heavy paths. Edge Cases: Handles missing optional inputs with defaults; clamps inputs to supported ranges; flags infeasible targets (e.g., clock too high for given width) and returns warning codes; if base data unavailable, uses conservative estimates. Industry/Region & Localization: Adheres to standard FPGA design terminology and timing units (ns, MHz); supports common regional measurement conventions; outputs are interpretable for global engineering teams. Assumptions & Exclusions: Assumes System Generator-like modeling context and does not perform full place-and-route; not a substitute for vendor synthesis reports; assumes input values originate from high-level design specs rather than post-implementation data.
