Mirabilis Design provides performance analysis and architecture exploration solution for the design of electronics and real-time software. The product, VisualSim, is a graphical modeling and simulation environment. Models of the proposed system are constructed by engineers in VisualSim using parameterized modeling library and C/C++/Java/SystemC/Verilog/VHDL. Designers and architects can conduct trade-off studies by varying parameter values, executing different input traffic stimulus and modifying the system configuration including the topology. The parameterized libraries contain traffic generators, statistics viewers, processing flows, resources, architecture components and application-specific functions. The outputs from VisualSim are a highly optimized design, executable specification and virtual platform to verify implementation.

The examples contained on the pages linked below demonstrates the model construction and trade-off possibilities in VisualSim. User can experience VisualSim by clicking on the model links. The leads to a new Browser page that instantiate a pre-built VisualSim model to display and execute within the Web Browser. The user can click on an icon in the graphical model to view the parameters. Click on "GO" button to start the simulation. Double-click on names (model parameters) in the model view, change the values and execute the simulations.

VisualSim Architect, the desktop application, was used to construct these models. Over 250 additional models are shipped with VisualSim. To experience model-based design using VisualSim, request for an Evaluation or send us an email.

   Hardware-Software Partitioning of mobile platforms
This model is used to define different use cases supported by the mobile phone. These uses cases have different behavioral flows that are mapped to a variety of architecture resources.

   WLAN 802.11
This model accurately describes the 802.11 MAC implementation. In addition, it also provides the hooks required to add emerging Physical layer implementation. This model contains all the 802.11 signaling, transmitter, receiver, nodes and Access Point. This also handles packet fragmentation. The model is fully parametereized for the user to modify and run additional scenarios.

HW-SW Tradeoff studies for implementing an application on a Wireless Standard This example shows the execution of an application as a series of instructions on either a custom-IC or using discrete components on a board. The hardware and software model has been construction on top of a Wireless LAN systems.

Bluetooth
This model is timing and signal accurate implementation of a Master-Slave Bluetooth implementation. All of the details described for the Wireless LAN above are equally applicable here.

Channel Modeling
This model studies the impact of a communication channel on a simple protocol called stop-and-wait. The next packet is not sent until acknowledgment is received from the earlier packet.

Encoder & Decoder
This model has custom-coded implementation of the Viterbi Decoder and Convolution Encoder. The results are plotted.

A/D Converter
Implements a Sigma-Delta A/D Converter with a second order sub-system.
