Optimize your 5G NR O-RAN Split 7.2X design with EIC cutting-edge PRACH Design and Verification Suite

Overview

Key Features

• Overview:
  • Comprehensive Support: All PRACH formats and configuration indexes described in 3GPP 38.211 are fully supported.
  • Versatile Sequences: Length-139 and length-839 sequences are included.
  • Frequency Multiplexing: Capable of decoding up to 8 frequencies multiplexed PRACHs.
  • Flexible Subcarrier Spacing: Supports both 15 and 30 kHz PRACH subcarrier spacing for short formats.
• PRACH MATLAB Model:
  • O-RAN Compatibility: Input stimuli generation and C-Plane Section Type: 3 message generation for each PRACH occasion.
  • Configurable Input: Option to constrain the number of frames and resource blocks.
  • Advanced Signal Processing: Three signal processing chains implemented:
    • 1. Full frequency-domain PRACH extraction in double data format for golden reference.
    • 2. Hybrid frequency and time-domain PRACH extraction in double data format using MATLAB’s high-level functions for proof of concept.
    • 3. Hybrid frequency and time-domain PRACH extraction in fixed-point data format for RTL implementation.
  • Precision PDP Calculation: Performed at the end of each processing chain.
  • Configurable Bit Reduction: Allows adjustment of bit reduction amounts at each module’s output.
  • Data Dumping: Possible after each module.
• PRACH RTL Design:
  • Direct Implementation: RTL implementation of the MATLAB model’s fixed-point signal processing chain.
  • Extensive Frequency Resource Extraction: Capable of extracting up to 8 PRACH frequency resources.
  • Detailed Information: Provides CC ID, Section ID, and RU Port ID information.
  • Flexible Decimation: Supports 1 to 96x decimation.
  • Robust FFT Support: Handles 256 to 8192 point FFT after decimation.
  • Industry Standard Interface: Utilizes AXI4-Stream interface.
• PRACH RTL Test Environment:
  • AXI4-Stream IQ Data Driver: Takes input stimuli generated by the MATLAB model and feeds them into the RTL signal processing chain.
  • C-Plane Section Type: 3 Message Driver: Processes C-Plane messages generated by the MATLAB model and feeds them into the RTL signal processing chain.
  • MATLAB Model-Based Reference: The PRACH Design and Verification Suite uses the MATLAB model as a reference, allowing for the comparison of outputs from sub-blocks with MATLAB references. This feature simplifies the debugging process and enhances verification accuracy.
  • Extensive Test Scenario Support: Provides RTL verification scenarios for all PRACH formats and indexes.
