Geoffrey James's recent article provides
a succinct description of several important trends that are driving
customers towards system level design and verification. He makes
several points about shifts in technology and methodology, and the fact
that the RTL remains the golden source even for today's ESL flows.
is necessary, but not sufficient. Customers will require nearly a
decade to make a transition to TLM as the golden source for design
flows. In that period we must support mixed RTL and TLM flows. Both
design IP creation and reuse, as well as functional verification, must
support multiple levels of abstraction.
that can handle estimation, planning, analysis, synthesis, and
verification with mixed TLM and RTL IP is a requirement for mainstream
customer adoption. But more important will be methodology that helps
customers achieve both a TLM-driven design and verification solution,
and reuse existing RTL IP.
