Embedded Development using VisSim - Visual Solutions
"VisSim is a block diagram language for creating complex nonlinear dynamic systems. To create a model, simply drag blocks in the workspace and connect them with wires. Then click the Go button to initiate your simulation. The response is instantaneous."
"VisSim's tightly integrated development platform makes it easy to pass freely among the stages of model construction, simulation, optimization, and validation. This means you can create virtual prototypes on your desktop and make sure they're working properly before committing to the design."
VisSim - Digital Power Designer
VisSim/Digital Power Designer provides high level blocks for simulation and code generation of power supply and digital power components and controls. VisSim/Digital Power Designer blocks let you develop a working controller which can be directly downloaded to the MCU for digital power applications.

Lab Test Bench and Breadboard testing needs to be done along with analog simulation. Power and mixed signal design too, needs to be verified on board. This is more true for a new design lab or new engineers. Experienced designers will not make many mistakes as design blocks would be in their collections or in their knowledge base. It is this knowledge that can build the simulator itself, this makes the simulator as skilled as the designer but also limited to his or that firm's experience. In a full digital design, simulation does a more complete Virtual Test bench role.
A simulation tool can help you test the blocks and helps catch some design and concept errors. When you build a live breadboard prototype, some real issues facing your design can emerge.
Spice is a analog design aid and helps mixed design circuit simulation, See the Spice homepage.
SPICE (Simulation Program with Integrated Circuit Emphasis) is a general purpose analog electronic circuit simulator. It is a powerful program that is used in IC and board-level design to check the integrity of circuit designs and to predict circuit behavior. - Wikipedia

Automatic Integrated Circuit Modeling Spice (AIM-Spice) is a version of SPICE, the most popular analog circuit simulator.
AIM-Spice is a new version of SPICE running under the Microsoft Windows and Linux operating systems. AIM-Spice for Windows is capable of displaying graphically the results of a simulation in progress, a feature that allows the operator to terminate a run based on an instant information on intermediate simulation results.
SPICE - The simulator was developed at the University of California, Berkeley, and was first released in 1972. Many scientists at Berkeley and other institutions contributed to the development and improvement in subsequent versions of SPICE.
