Hi,
I would like to ask if there is a way of filtering uvm_info messages output during simulations.
I am interested in messages coming from one particular uvm_component.
Does SimVIsion have a feature like that?
Thanks,
vito

changing the name of waves.trn file
Hi,
Does any one know how to change the name of waves.trn located in waves.shm directory during simulation ?
Is there a command-line option that can be passed to irun to do this ?
This is because every time I run a simulation using irun, the old waves.shm/waves.trn file is overwritten by the new one.
Thank you

One hot assertion in RTL
Hi,
What is the best way to add one hot assertion on a bus in verilog?
Ex: Wire [9:0] one_hot_wire; Only one of the bit of this wire is supposed to go high in the simulation otherwise it should fail.

In fact, I'm using the syntaxe given in the help example of IMC HELP as follow:

exclude -inst lib.inst_a(rtl):inst_b:inst_c -toggle rst (NOT WORKING: *W,NOMATCH: No matching entities found for argument 'lib.inst_a(rtl):inst_b:inst_c/rst)

Accessing vplan attributes from console
Hi All,
Does anyone know anything about the API to access vplan attributes from the console or from an e program ?
Specifically I want to be able to output this data in an arbitrary text format.
I know that I can already export a csv file using some batch API commands as shown below but I would like to directly access the parameters such as NAME and SIMULATION_ABSOLUTE_GRADE and then output them myself.
Has anyone done this or does anyone know how to do it ?
<'
extend global {
dump_vplan ( result_file_name:string=NULL) is {
vm_manager.set_global_config("time_format","%F %T");
if result_file_name == NULL { result_file_name = "results.csv"; };
var all_sessions := vm_manager.get_all_sessions();
var params: vm_export_vplan_parameters = new;
params.set_vplan_tree_depth(1);
params.set_information_kind(SECTIONS);
var attrs: list of vm_vplan_attribute_t;
attrs.add(NAME);
attrs.add(SIMULATION_ABSOLUTE_GRADE);
params.set_attributes(attrs);
params.set_target_file(result_file_name);
params.set_override_target_file(TRUE);
vm_manager.export_vplan(params, all_sessions);
};
};

Assertion detect *WORNG* fell of line due to gated clock
Assertion detect *WORNG* fell of line due to gated clock
Simulation assume line was high and on the posedge of clock the line is constant low and detect it as FELL and assertion is active due to that and cycle after fail!
assert property ( @(posedge TxByteClkHS) disable iff(!rst_sys_n)
$fell(TxRequestHS) |=> $fell(TxReadyHS) );
Tought to add ##1 cycle delay before every assertion, but the solution is not very good.

I am intending to use a MATLAB predictor model in the system verilog verification frame work.
Can I get some help as to how I can simulate MATLAB concurrently with the SV frame work so that i can input the same random stimulus to the DUT as well as the MATLAB predictor module.
