Waveforms allow users to view selected simulation signals at higher speeds and with better resolution than that offered by custom device channels. Custom device channels perform single-point acquisition, a non-buffered operation that occurs at the rate at which the Real-Time CPU runs. Waveforms, on the other hand, read and stream FPGA-generated data at rates faster than the Real-Time CPU.

For each Waveform, the following mapping options are available at edit time:
Waveform Settings | ||
Source | Filters the list of available elements to be mapped to the waveform channel. The available options are defined by the selected Hardware Configuration, however it is typical to see the following options by default: | |
| No signal is mapped to the Waveform. | |
| eHS Measurements made in the circuit model. In the Element dropdown, select the name of the measurement to map. | |
| Output channels of the Machine Model. In the Element dropdown, select the name of the channel to map. | |
| Analog Input channels of the PXI card. In the Element dropdown, select the index of the AI channel to map. | |
Element | The name or index of the channel to be mapped to the Waveform. The options available in this dropdown depend on the selected Source. | |
Sample Rate (S/s) | Sample rate of the data acquisition performed on the FPGA signals by the waveform engine. This Sample Rate is per channel, and applies to all the Waveform channels defined. See Waveform Data Transfer and Streaming Rate for more information. | |
