... implementation details. Behavioral modeling is used in the initial stages of a design process to evaluate various design-related trade-offs. Behavioral modeling is similar to C programming ... programming in many ways. • Structured procedures initial and always form the basis of behavioral modeling. All other behavioral statements can appear only inside initial or always blocks. An...
