Odatix

Odatix is a powerful tool designed to facilitate implementation and validation of configurable digital designs across multiple FPGA and ASIC tools, including Vivado, OpenLane, and Design Compiler.

Odatix enables designers to:

• Explore different architectural configurations using parameter definition and generation.
• Automatically find the maximum operating frequency (Fmax) of any digital design.
• Run logical synthesis for every desired clock speed of any digital design.
• Run simulations to validate and benchmark your design.
• Run simulation/synthesis jobs in parallel to get results faster.
• Compare architectures based on multiple metrics, such as Fmax, power consumption, and resource utilization.
• Visualize results interactively in a web-based dashboard.

🚀 Key Features

✅ Architecture Exploration

• Easily define and generate multiple design configurations, regardless of the HDL used (VHDL, Verilog, SystemVerilog, and even Chisel or HLS).

✅ Automated Synthesis

• Run synthesis on FPGA and/or ASIC tools for each configuration of a design on various targets.
• Perform custom frequency synthesis to analyze design behavior at specific clock speeds.
• Automatically determine maximum operating frequency (Fmax).

✅ Efficient Simulation

• Execute simulations for each configuration of a design.
• Validate functionality and gather benchmark results.

✅ Job Monitoring

• Track parallel synthesis/simulation jobs progress and logs in real-time.
• Start, pause, resume, or kill jobs effortlessly.

✅ Interactive Results Exploration

• Analyze results visually with built-in support for line, column, scatter, and radar charts.
• Export charts in vector (SVG) or raster (PNG, JPEG, WEBP) formats.
• Customize the appearance of your figures with different themes.

✅ Quick Start

• Install Odatix easily from PyPi with pip.
• Use built-in examples and step-by-step tutorials to get started quickly.
• Need help? Contact us or open an issue on GitHub.

💡 Highlights

🖥️ Job Monitor

• Track all running jobs (synthesis or simulation) in a user-friendly interactive interface.
• Live updates of job progress and logs.
• Full control: start, pause, resume, or kill jobs at any time.

📊 Odatix Explorer

• Interactive web interface for deep result exploration.
• Compare architectures visually using line, column, scatter, or radar charts.
• Export high-quality charts in both raster (PNG, JPEG, WEBP) and vector (SVG) formats.

Examples:

• Line chart of a metric (Fmax here) for multiple designs and configurations on different targets (FPGA here):

• Column chart of a metric (Fmax here) for multiple designs and configurations on different targets (FPGA here): FPGAFPGA

• Radar chart of a metric (Fmax here) for multiple designs and configurations on different targets (FPGA here):

• Compararison of a metric (power consumption here) at different operating frequencies for multiple designs and configurations on different targets (FPGA here):

• Scatter plot: Correlation between 2 metrics (power consumption and Fmax here)for multiple designs and configurations on different targets (FPGA here):

• Scatter 3D plot: Correlation between 3 metrics (LUT count, register counter and Fmax here) for multiple designs and configurations on different targets (FPGA here):

• Overview: Comparative analysis of multiple implementation metrics for multiple designs and configurations on different targets (FPGA here):
