It is simulating fine in Icarus. I tried to integrate this module into the block design (consisting of Xilinx IP cores like AXI4 and Processing System and some custom Verilog modules) using the 'Add Module' dialog, but SystemVerilog seems to be incompatible since the modules are only shown greyed out after unchecking 'Hide incompatible module'. Is mostly like a module block except as stated above. The idea of a program block is to create a clear separation between test and design. In earlier versions of SystemVerilog (pre IEEE 1800), instantiation of a class was often limited to program blocks. This emphasized the division of test and design.
- Typically what I do is set the digital block view to symbol in the hierarchy editor. I then include a file in AMS Options Option files that has all of the.v/.sv files needed for the digital block. Running at this point will give syntax errors in the.sv file because the simulator does not know how to handle certain systemVerilog constructs.
- R 7.3.1 At most one module per file R 7.3.2 File naming conventions R 7.3.3 Separate analog, digital, and mixed-signal Verilog files R 7.3.4 HDL Code items naming convention R 7.3.5 Document abbreviations and additional naming conventions R 7.3.6 Global text macros include module name R 7.3.7 Instance naming conventions.
- Module latch (output logic 31:0 y, input 31:0 a, input enable); always @(a iff enable 1) y block that is used to model combinational logic, forgetting an else leads to an unintended latch. To avoid this mistake, SystemVerilog adds specialized alwayscomb and alwayslatch.
Online course in Systemverilog for functional verification
Online course in SystemVerilog for Functional Verification is a 12 weeks course structured to enable engineers develop their skills in full breadth of systemverilog features. VT-SVO course covers all aspects of functional verification including constrained random verification, assertion based verification and coverage driven verification. VT-SVO course has been framed to fit to every functional verification engineer requirements and also targeted for graduates aspiring to make career in VLSI Front End domain. Course approaches by teaching basic concepts to most advanced aspects of SV with relevant examples to enable easier understanding of concepts.
VT-SVO course also includes training industry standard protocols like AXI, AHB, etc, with emphasis on teaching industry standard AXI protocol and developing Verification IP for same. Course also includes 1 industry standard project. All these projects are executed from scratch with students working on complete flow starting from specification reading, feature listing down, testbench architecture creation, component coding and testcase development till verification closure using coverage and regression as verification closure criteria.
VT-SVO course also includes multiple weeks of Lab sessions to enable student put effort in doing above projects from scratch.
