• What is the budget for the product?

• What are the physical size limitations?

• How complex is the design (gate count, if known)?

• What is the maximum frequency for the design?

• What loads will the system be driving?

• What other components are needed to complete your design?

• What experience have you or your group had to date in the design of digital systems?
