The 5G library in VisualSim Architect enables the simulation and architectural analysis of modern wireless communication systems. This model replicates the critical elements of a 5G network, providing insights into system behavior during data transmission and reception. It allows early-stage validation of design decisions related to physical and MAC layers of 5G technology.

Overview

The 5G model in VisualSim offers a detailed breakdown of physical and data link layer operations:

  • MAC-PHY Interface: Manages coordination between the Medium Access Control (MAC) layer and the Physical (PHY) layer.
  • Bit Scrambler & Descrambler: Introduces randomness in data streams to improve signal reliability and minimize pattern-based interference.
  • FEC LDPC Encoding & Decoding: Implements Low-Density Parity Check (LDPC) coding for robust forward error correction, reducing retransmissions.
  • OFDM Modulator & Demodulator: Simulates Orthogonal Frequency-Division Multiplexing to enable high data rate transmission over wireless channels.
  • Massive MIMO Antennas: Models multi-antenna transmission and reception for enhanced capacity, beamforming, and spatial multiplexing.
  • Interleaver & Deinterleaver: Reorders data bits to resist burst errors and improve overall transmission quality.

Supported Standards

Tied to the specification released by 3GPP. The model is customizable to align with specific implementations.

Applications

This model is suitable for:

  • Evaluating modulation and coding effects on 5G signal transmission
  • Measuring latency, jitter, and throughput under various traffic and channel conditions
  • Exploring trade-offs in physical layer design for device and base station architectures
  • Testing data rate scaling, error rates, and signal interference for high-density environments
  • Validating chip design decisions for 5G front-end and baseband systems

Use cases include base station architecture exploration, modem design validation, and AI-assisted wireless protocol testing.

Integrations

VisualSim 5G models integrate seamlessly with the following VisualSim libraries and IP models:

  • Network-on-Chip (NoC) for SoC interconnect
  • AI/ML accelerators for smart antenna control and beamforming
  • CPU cores and memory models for system-level simulation
  • TSN or Carrier Ethernet for edge-to-core integration

Note: No dedicated “5G component” in the VisualSim component library. Model is built using reusable IP blocks.
