Hello, I downloaded the latest systemC systemc-2.3.3, compiled and installed it locally. I also ran some of the tests and an example, and it all works fine. This is on RHEL 6.0, using GCC 6.3. During the compile, I got warnings like this: libtool: warning: library '/nis/asic/apps2/linux/sw/verilog/xcelium/XLM_20.09.011/tools.lnx86/cdsgcc/gcc/6.3/install/lib/../lib64/libstdc++.la' was moved. Searching on that warning (or similar) didn't turn up much, and the compile/install all works fine, so I thought it was no big deal. However, this same warning seems to be triggering an error for UVM-SystemC compile. I've downloaded: uvm-systemc-1.0-beta3, and I'm compiling it by pointing to the above newly compiled/installed systemC. ../configure --prefix=/nis/asic/gls_dump/ricardga/uvm-systemc-1.0-beta3

Hi All, Just wanted to check if the UVM sequence macros (UVM_DO_ON_WITH and UVM_DO_WITH) which support randomizing the sequence object are yet supported by UVM-SC or not? If not, what is the best way to add some randomization in the framework? I saw a post where there are some snippets (link given below) using scvx_rand_object class but I am not sure where to find this(didn't find it in latest SCV and UVM-SC libraries). http://nascug.org/events/20th/1-NASCUG20-UVMforSystemC-Karsten.pdf Also, I get errors while using plain UVM_DO_ON macros. Is it expected? The same works fine with ahb_wr_seq->start(top_env->agent->ahb_sequencer_inst); I have registered the sequence class with factory already. UVM_DO_ON(ahb_wr_seq,top_env->agent->ahb_sequencer_inst); Error message says: /nfs/iind/disks/ba_bdl_xplore_disk001/am5/UVM_SC/uvm-systemc-1.0-alpha1/src/uvmsc/macros/uvm_sequence_defines.h:150:31: error: expected type-specifier before ‘typeof’ SEQ_OR_ITEM = dynamic_cast< typeof(SEQ_OR_ITEM) >(create_item(objw__, SEQR, "SEQ_OR_ITEM")); ^ /nfs/iind/disks/ba_bdl_xplore_disk001/am5/UVM_SC/uvm-systemc-1.0-alpha1/src/uvmsc/macros/uvm_sequence_defines.h:115:3: note: in expansion of macro ‘UVM_CREATE_ON’ UVM_CREATE_ON(SEQ_OR_ITEM, SEQR) \ ^ /nfs/iind/disks/ba_bdl_xplore_disk001/am5/UVM_SC/uvm-systemc-1.0-alpha1/src/uvmsc/macros/uvm_sequence_defines.h:80:3: note: in expansion of macro ‘UVM_DO_ON_PRI_WITH’ UVM_DO_ON_PRI_WITH(SEQ_OR_ITEM, SEQR, -1, "") ^ ahb_basic_test.h:59:11: note: in expansion of macro ‘UVM_DO_ON’ UVM_DO_ON(ahb_wr_seq,top_env->agent->ahb_sequencer_inst); Appreciate any help here. Thanks Akhila

Does UVM_SC has support for coverage bin and coverpoints? Want to know if user can add functional coverage classes. Thanks Akhila

Hi Guys, I have a simple framework for an IP level testbench, written using UVM-SC libraries. The intent is to be able to pump basic AHB write/read request to the DUT(in System C) using this BFM. I have created all basic components, snippet for which are pasted below. I have an ahb_sequencer, which is just an extension oh uvm_sequencer with specific ahb_transaction type. In ahb_driver run_phase is as under: void run_phase(uvm::uvm_phase phase) { REQ req, rsp; for(;;) { UVM_INFO(this->get_name(), "run_phase Entered", UVM_LOW); this->seq_item_port->get_next_item(req); rsp.set_id_info(req); this->seq_item_port->item_done(); this->seq_item_port->put_response(rsp); } } In ahb_env, driver and seqr are connected and sequences are started. class ahb_basic_env : public uvm::uvm_env { public: ahb_driver<ahb_transaction>* ahb_driver_inst; ahb_sequencer<ahb_transaction>* ahb_sequencer_inst; ahb_basic_write_sequence* ahb_wr_seq[NUM_SEQS]; UVM_COMPONENT_UTILS(ahb_basic_env); ahb_basic_env( uvm::uvm_component_name name) : uvm::uvm_env(name) { std::cout << sc_core::sc_time_stamp() << ": constructor " << name << std::endl; } void build_phase(uvm::uvm_phase& phase) { std::cout << sc_core::sc_time_stamp() << ": build_phase " << name() << std::endl; uvm::uvm_env::build_phase(phase); UVM_INFO(this->get_name(), " is ACTIVE", UVM_LOW); ahb_sequencer_inst = ahb_sequencer<ahb_transaction>::type_id::create("ahb_sequencer_inst",this); assert(ahb_sequencer_inst); ahb_driver_inst = ahb_driver<ahb_transaction>::type_id::create("ahb_driver_inst",this); assert(ahb_driver_inst); for (int i = 0; i < NUM_SEQS; i++) { std::ostringstream str; str << "ahb_basic_write_sequence" << i; ahb_wr_seq = new ahb_basic_write_sequence(str.str()); } } void connect_phase(uvm::uvm_phase& phase) { std::cout << sc_core::sc_time_stamp() << ": connect_phase " << name() << std::endl; uvm::uvm_component::connect_phase(phase); ahb_driver_inst->seq_item_port(ahb_sequencer_inst->seq_item_export); } void run_phase(uvm::uvm_phase& phase) { phase.raise_objection(this); std::cout << sc_core::sc_time_stamp() << ": run_phase Entered " << name() << std::endl; SC_FORK sc_core::sc_spawn(sc_bind(&ahb_basic_env::start_sequence, this, 0)), sc_core::sc_spawn(sc_bind(&ahb_basic_env::start_sequence, this, 1)), SC_JOIN std::cout << sc_core::sc_time_stamp() << ": run_phase Exited " << name() << std::endl; phase.drop_objection(this); } void start_sequence(int n) { ahb_wr_seq[n]->start(ahb_sequencer_inst, NULL); } }; The sequence uses wait_for_grant() and start_item() calls to initiate the transaction: class ahb_basic_write_sequence : public uvm::uvm_sequence<ahb_transaction,ahb_transaction> { public: ahb_basic_write_sequence( const std::string& name = "ahb_basic_write_sequence") : uvm::uvm_sequence< ahb_transaction,ahb_transaction > ( name ) { std::cout << sc_core::sc_time_stamp() << ": constructor " << name << std::endl; } UVM_OBJECT_UTILS(ahb_basic_write_sequence); void pre_body() { // raise objection if started as a root sequence if(this->starting_phase != NULL) this->starting_phase->raise_objection(this); } void body() { ahb_transaction* req_pkt; ahb_transaction* rsp; unsigned transaction_numb; UVM_INFO(this->get_name(), "Starting sequence ahb_basic_write_sequence", uvm::UVM_INFO); transaction_numb = 10; for(unsigned int i = 0; i < transaction_numb; i++) { req_pkt = new ahb_transaction(); rsp = new ahb_transaction(); UVM_INFO(this->get_name(), "Sending transaction from sequence ahb_basic_write_sequence", uvm::UVM_INFO); req_pkt->haddr = 0x100000 + 4*i; req_pkt->hwrite = 1; //req_pkt->hwrite = ahbConfig::WRITE_XACT; req_pkt->htrans = 2; //req_pkt->htrans = ahbConfig::HTRANS_NONSEQ; req_pkt->hwdata = (sc_uint<32>)(0xAAAABBBB + 4*i); req_pkt->hsize = ahbConfig::HSIZE_WORD; this->wait_for_grant(); UVM_INFO(this->get_name(), "Calling send_request from sequence ahb_basic_write_sequence", uvm::UVM_INFO); this->send_request(req_pkt); UVM_INFO(this->get_name(), "Getting response from sequence ahb_basic_write_sequence", uvm::UVM_INFO); this->get_response(rsp); } UVM_INFO(this->get_name(), "Finishing sequence", uvm::UVM_INFO); } void post_body() { // drop objection if started as a root sequence if(this->starting_phase != NULL) this->starting_phase->drop_objection(this); } }; But when i run the code, it gets stuck at wait_for_grant() call and also I don't see the run_phase prints from the driver class. The output looks something like this: Starting SC tests ... Running AHB tests 0 sIn dut UVM_INFO @ 0 s: reporter [RNTST] Running test ... 0 s: build_phase tb UVM_INFO ahb_basic_env.h(65) @ 0 s: tb [tb] is ACTIVE 0 s: constructor ahb_sequencer_inst 0 s: constructor ahb_driver_inst 0 s: constructor ahb_basic_write_sequence0 0 s: constructor ahb_basic_write_sequence1 UVM_INFO ahb_driver.h(53) @ 0 s: reporter [ahb_driver_inst] build_phase Entered 0 s: connect_phase tb Info: (I804) /IEEE_Std_1666/deprecated: all waits except wait() and wait(N) are deprecated for SC_CTHREAD, use an SC_THREAD instead 0 s: run_phase Entered tb UVM_INFO ahb_basic_write_sequence.h(66) @ 0 s: reporter [ahb_basic_write_sequence0] Starting sequence ahb_basic_write_sequence UVM_INFO ahb_basic_write_sequence.h(76) @ 0 s: reporter [ahb_basic_write_sequence0] Sending transaction from sequence ahb_basic_write_sequence UVM_INFO ahb_basic_write_sequence.h(66) @ 0 s: reporter [ahb_basic_write_sequence1] Starting sequence ahb_basic_write_sequence UVM_INFO ahb_basic_write_sequence.h(76) @ 0 s: reporter [ahb_basic_write_sequence1] Sending transaction from sequence ahb_basic_write_sequence Any idea why is this happening? wait_for_grant() should unblock when driver takes the request right? Not sure why isnt the driver getting the request. Appreciate your help here! TIA PS: Attached the files for reference. Akhila ahb_basic_write_sequence.h ahb_basic_env.h ahb_driver.h ahb_sequencer.h
