Installation

Please install the following dependencies manually:

Clone the corresponding repositories,

$ git clone --recursive  <PATH>

enter the directory and execute

$ mvn install

The documentation can be created with

mvn javadoc:javadoc

and accessed at ./target/apidocs/index.html.

Dependencies

Environments

  • Single-Ended Operational Amplifier

    The environment SingleEndedOpampEnvironment is utilized to extract common performances of a single-ended operational amplifier.

  • Nand-Gate with 4 inputs

    The environment Nand4Environment is utilized to extract the switching thresholds of a NAND gate with 4 inputs.

  • schmitt trigger

    The environment SchmittTriggerEnvironment is utilized to extract the thresholds and propagation delays of a schmitt trigger.
