    I joined Cadence in July 2000 and was immediately put on a three-month training to learn and understand the simulator tools. There were formal training sessions, and I had a mentor who I could ask all my queries. But most of the times, I was on my own, as "learning by doing" was the motto of my mentor. After completing 14 years at Cadence, I can tell you that it works great, especially in cases where the tool is also…

    One question we often hear from experienced physical design engineers migrating to Encounter Digital Implementation System is, "How do I get up to speed on the tool as quickly as possible?" They understand place-and-route (P&R) concepts so they often don't need to attend a full training class over several days.

    Frequently, they may utilize Rapid Adoption Kits (RAKs), documentation, and other material…

    I wrote earlier that the sheer vastness and potential for IoT designs require a different way of thinking about system implementation. There just isn't a single controller architecture that meets all IoT requirements, such as multiple sensors, an innovative user experience, wireless protocol support, and various security requirements.

    And if a single controller architecture is not the answer, do we just lean on other…

    A test point is a location within an electronic circuit that is used to either monitor the state of the circuitry or to inject test signals. Test points have two primary uses:

    • During manufacturing they are used to verify that a newly assembled device is working correctly. Any equipment that fails this testing is either discarded or sent for rework.
    • After sale of the device to a customer, test points may be used at a…

    Suppose you have two verification components, each driving its own portion of the DUT (for example, two protocols driving a DUT, one implemented in e and the other in System Verilog).

    In this case, you would have two separate sequence-driven, end-of-test mechanisms - one for each framework.

    An issue arises when one of the frameworks drops its last TEST_DONE objection. In this case, that framework will begin simulation…
