Uvm analysis port in sequence. uvm_analysis_export(s) can be viewed as a transfer port.
Uvm analysis port in sequence Here we use two uvm_analysis_exports which connected to both the input and output monitors’ analysis_port to retrieve the observed input and output transactions. You should never extend uvm_sequencer. I have used RAL previously where my extended_sequence_item wasn’t parameterised and was working with the same code as shown below. `uvm_info(get_type_name(),$sformatf(" Inside write method. parameters are fine for certain things but they come with the downside that paramterized classes are only assignment compatible if ALL parameters are the same. In your specific cas I do not really understand how you are generating the seq_item in (1). Most of the analysis take places dynamically as the simulation runs, but some analysis can be done after the run phase ends. The write function needs to store the received information somehow, eg by writing it to a queue (which would also be a data member of your extended sequencer class). Typical usage is as a buffer between an uvm_analysis_port in an initiator component and TLM1 target component. "bus_in" is a port that is provided from UVM The base class for drivers that initiate requests for new transactions via a uvm_seq_item_pull_port. uvm_analysis_export: Exports a lower-level uvm_analysis_imp to its parent. seq_item_export); // driver to sequencer mapping one to one connection only .

This paper explains UVM analysis port usage and compares the functionality to subscriber satellite TV. sv" `include "apb_sequencer. If you need any additional information in your sequence, it should come from a sequence_item response or from your virtual sequence. The ports are typically connected to the exports of an appropriate sequencer component. Each call to write() gets implemented into a separate call to write() in the subscriber. UVM - Universal Verification Methodology Jan 25, 2018 · 1) Derive from uvm_subscriber, override the write function, which is then called over the built-in analysis port. Use the analysis_port of the monitor to send the transaction(s) to another uvm_subscriber - probably with a tlm_fifo in it. If things are done in different phases, then you can guarantee that something done in a later phase will happen before something done in an earlier phase.

See it working here: BTW don’t use the field macros. This image gives explanation of uvm_analysis_port. It should be used as-is, parameterized with your uvm_sequence_item type. write() will never happen simultaneously; they will get called in some undefined yet deterministic order. making it a parameter is only required if you need compile time or elab time constants (bit width or similar). Learn about how you can effectively use a UVM sequence library to store and randomize the order in which sequences are called. Here are my answers to your questions. Note: Both uvm_seq_item_pull_port and uvm_seq_item_pull_export are parameterized classes with REQ and RSP sequence items. They serve as a data transfer objects from ports to implementations, as we cannot connect analysis_imp to another analysis_imp. In our case here, we have try connecting same port implementation. Send the response back to the sequence. So ultimately, the analysis port of agent needs to be connected to the fifo of scoreboard. svh" `include "apb_rw.

You can create an analysis_port in your driver. Nov 21, 2017 · Hi Prawin, I will tell you what I understood from your question. While uvm_tlm_fifo is used when put/get ports are used, that is, for one-to-one communication. So, do I need to somehow bring this data from agent's monitor to my test/sequence class? I know that monitor has an analysis port and it can be used to send received data to scoreboard for checking. The driver has uvm_seq_item_pull_port which is connected with uvm_seq_item_pull_export of the associated sequencer. For those cases, I recommend checking the analysis import connections during the end_of_elaboration_phase: `CHECK_PORT_CONNECTION(my_analysis_imp) Where the above macro is defined like: An analysis_fifo is a uvm_tlm_fifo with an unbounded size and a write interface. If you build a get_port into it (or whatever meets your needs), then you just have to pass that handle to your sequence. Apr 30, 2024 · How does write work for an analysis port? I had some code that I wrote that looked like the following: (note that m_predictor_ssi_ap is eventually connected to a fifo in my comparator so what I want to see is the reference transactions stacked in groups of 4 ) uvm_analysis_port #(some_seq_item) m_predictor_ssi_ap; m_predictor_ssi_ap = new("m_predictor_ssi_ap", this); some_seq_item ref_trans UVM `uvm_do sequence macros UVM sequence - start() UVM sequence - do macros Macros for pre-existing items UVM Virtual Sequence UVM sequence library UVM Sequence Arbitration 8. uvm_analysis_port can be open without any implementation of uvm_analysis_imp or uvm_analysis_export.
