1. Introduction The UVM Primer is an introductory book on UVM, written and published by Ray Salemi. It is a free and open source project. The code can be downloaded from GitHub. This book is only more than 100 pages long. It is a step-by-step in-depth study around TinyALU. It is very suitable for beginners of UVM. Of course, it also needs to ...

preface UVM is a methodology of IC Verification. The basic framework of verification environment built by UVM is similar. Therefore, the basic framework of verification environment of UVM can be generated through script. This paper mainly introduces a script uvmgen provided by synopsys in vcs tool. Through this script, a complete set of ...

1, event 1.1 differences between event in UVM and event in SV The difference between event in UVM and event in SV is that the same object is mainly IPC in SV. UVM is not limited to one object. In order to solve the synchronization problem of different component threads, it also needs to maintain the closure of UVM. Therefore, it establish ...

1. Why use sequence The main function of sequence is to facilitate the generation of transactions for testing. It is unreasonable to directly generate a transaction in the driver during verification. The reasons include: The function of the driver is to convert the transaction into an excitation signal. If the function generating the transact ...

Summary of the strongest sequence related macro operations in history 1, Sequence macro The following code is a natural code description of the execution process of the start() method. You can see the sequence relationship and conditions of their execution: sub_seq.pre_start() (task) sub_seq.pre_body() (task) if call_pre_pos ...
