Monitors

mmWaveLink Monitor Module is responsible for providing APIs for FECSS analog monitor.The Monitor Module mainly supports below SET/GET APIs to FECSS, these monitors can aid in functional safety qualification.

• APLL & SYNTH Monitors
• RX and TX loopback Monitors
• TX Power Monitor
• TX Ballbreak Monitor
• RX Saturation Live monitor
• Synth Frequency Live Monitor
• Internal Signal DCBIST Monitors
• Rx Saturation Live Monitors and Synth Frequency Monitors

Steps to run Monitors

• Add below commands to cfg where we need monitors. Eg.
  

  enableRFmons 0x0000000606060607
  monPllCtrlVolt 0x03 0.2 1 0.1 1.45
  monTxRxLbCfg 3 58.0 2.2 -26 -26 -3 3 -20 20 -3 3 -30 30 -3 3 -30 30
  monTxnPowCfg 0 60.0 2.2
  monTxnPowCfg 1 60.0 2.2
  monTxnBBPowCfg 0 60.0 2.2 -6 3
  monTxnBBPowCfg 1 60.0 2.2 -6 3
  monTxnDcSigCfg 0 60.0 2.2 0x3
  monTxnDcSigCfg 1 60.0 2.2 0x3
  monRxHpfDcSigCfg 60.0 0 1.5 4.5
  monPmClkDcCfg 60.0 0xfffff

  
  
  
• To enable monitors in MMWAVE Demo and Motion & Presence Detection Demo enable the ENABLE_MONITORS Macro.
• gMmwMssMCB.rfMonRes has status of various monitors where 1 indicates PASS and 0 indicates FAIL.

Steps to run Live Monitors

• Live Monitors can be enabled through the sensorStart command.
  • sensorStart 0 0 < live monitors to be enabled > 0
• Live monitors to be enabled:
  • Bit[0] - Synth Frequency Monitor
  • Bit[1] - Rx Saturation Live Monitor Eg.
    To enable both Synth Frequency Monitor and Rx Saturation Live Monitor the following command can be used:

    sensorStart 0 0 3 0

    
    
    
• gMmwMssMCB.rfMonRes has status of various live monitors where 1 indicates PASS and 0 indicates FAIL.

Configuration (.cfg) File Format (CLI INTERFACE)

Each line in the .cfg file describes a command with parameters. The various commands and their arguments are described in the table below (arguments are in sequence)
