ADBMS6815
The ADBMS6815 is a virtualized integrated circuit designed to mimic the behavior of a real cell monitoring device. Within the VeriStand project, it is represented as a Device item in the configuration tree and is emulated on the FPGA of the Real-Time target upon project deployment. Each ADBMS6815 device in the Ring supports the monitoring of up to 12 battery cells, along with 7 GPIO channels. Passive balancing functionality is also included.
Section Channels
Expand the Device section in the configuration tree to display the following VeriStand channels. Channel values can be dynamically modified during execution.
Certain channel values are represented in hexadecimal or binary notation. Refer to How to Manage Hexadecimal and Binary Data in VeriStand for additional instructions.
Channel Name | Type | Format | Units | Default | Description |
---|---|---|---|---|---|
Enable | Input | Binary |
| 1 | Enables or disables the emulated device during execution.
|
CRC Check | Input | Binary |
| 1 | Enables or disables the cyclic redundancy check (CRC) of the command packet error code (PEC) and data packet error code (DPEC) of the SPI transmissions received by the emulated device.
|
Port A Enable | Input | Binary |
| 1 | Enables or disables SPI transmission on the Port A side of the emulated device. Use this channel to simulate a fault in the SPI communication.
|
Port B Enable | Input | Binary |
| 1 | Enables or disables SPI transmission on the Port B side of the emulated device. Use this channel to simulate a fault in the SPI communication.
|
Redundancy Fault | Input | Binary |
| 0 | Forces a digital redundancy fault on the emulated device and stores a digital redundancy fault code in place of the ADC result.
|
Vref2 | Input | Decimal | V | 0 | Emulates the VREF2 pin of a real device. |
Vref3 | Input | Decimal | V | 0 | Emulates the VREF3 pin of a real device. |
Vreg | Input | Decimal | V | 0 | Emulates the VREG pin of a real device. |
Vregd | Input | Decimal | V | 0 | Emulates the VREGD pin of a real device. |
Internal Die Temperature | Input | Decimal | °C | 0 | Emulates the Internal Die Temperature Measurement on the device, in degrees Celsius. The Internal Die Temperature is subsequently used to calculate the ITMP value stored in Status Register Group A. |
Sum of Cells | Input | Decimal | V | 0 | Emulates the Sum of All Cells Measurement on the device, in degrees Celsius. The Sum of All Cells is subsequently used to calculate the SC value stored in Status Register Group A. |
V- | Input | Decimal | V | 0 | Emulates the V- pin of a real device. |
ADOL Voltage Cell 7 | Input | Decimal | V | 0 | Sets the Cell 7 voltage measured by the emulated device when the ADOL command is received. |
Cell Measurement x | Input | Decimal | V | 0 | Emulates the cell voltage measurement of Cell x. This measurement is taken between pin Cx and pin C(x-1) on a real device. |
CVOW Cell x | Input | Decimal | V | 0 | Emulates the measurement of the change in voltage of Cell x due to the application of a squeeze current. This measurement is taken to enable the detection of open wires between the external cells. When the CVOW command is received from the SPI master, the values of these channels are written to the Cell Diagnostic Register groups on the emulated device. |
GPIO x | Input | Decimal | V | 0 | Emulates pins GPIO1 through GPIO7 of a real device. |
Serial ID | Input | Hexadecimal |
| 0 | Sets the Serial ID (SID) of the emulated device. To set the Default Value of this channel in the system definition, convert it to decimal notation. See How to Manage Hexadecimal and Binary Data in VeriStand Channels for more information. |
Open Wire Cx | Input | Binary |
| 0 | Emulates an open wire between the external cells. This open wire condition can be detected using the ADOW command.
|
STCOMM Reply Command | Input | Hexadecimal |
| 0 | When the STCOMM command is received from the SPI Master, the value of this channel is written to the COMM register of the emulated device. Map the command communication interface of an external device model, acting as an I2C or SPI slave, to this input channel. To set the Default Value of this channel in the system definition, convert it to decimal notation. See How to Manage Hexadecimal and Binary Data in VeriStand Channels for more information. |
STCOMM Reply Data | Input | Hexadecimal |
| 0 | When the STCOMM command is received from the SPI Master, the value of this channel is written to the COMM register of the emulated device. Map the data communication interface of an external device model, acting as an I2C or SPI slave, to this input channel. To set the Default Value of this channel in the system definition, convert it to decimal notation. See How to Manage Hexadecimal and Binary Data in VeriStand Channels for more information. |
Last Command Received | Output | Hexadecimal |
| 0 | Outputs the last command received from the SPI Master. |
Command CRC Check | Output | Binary |
| 0 | Binary flag indicating a Command CRC mismatch in the last transmission received from the SPI Master.
|
Data CRC Check | Output | Binary |
| 0 | Binary flag indicating a Data CRC mismatch in the last transmission received from the SPI Master.
|
PWM Discharge Control x | Output | Binary |
| 0 | Outputs the duty cycle of the PWM controlling the balancing switch for cell Cx. The value is represented in 4-bit binary format and corresponds to the PWMC Setting. This channel can be mapped to the input of an external cell model to regulate its discharge process. |
Discharge Cell x | Output | Binary |
| 0 | Binary flag outputting the status of DCC bit x in Configuration Register Group B.
|
WRCOMM Command | Output | Hexadecimal |
| 0 | Outputs the command stored in the COMM register as a result of the latest WRCOMM command received from the SPI Master. Map this channel to the input of an external device model acting as an I2C or SPI slave. |
WRCOMM Data | Output | Hexadecimal |
| 0 | Outputs the data stored in the COMM register as a result of the latest WRCOMM command received from the SPI Master. Map this channel to the input of an external device model acting as an I2C or SPI slave. |
