[PrimeTime] List of all registers

[maulin sheth]

Hello All,

Can anyone please help me to get list of all registers inside design at all hierarchical level in Synopsys PrimeTime?
I have tried with all_registers, but it reports nothing. Thereafter, I change top module to some internal module, thn it reports the registers which are in that module. So, how can I get it from top level? I want all registers from top level of all the sub-modules.

Thanks in advance.

I think you can try like
get_cells -of_object <ref_names of registers> *

get_cells -filter {is_sequential == "TRUE"} *

Thanks for help.
But sorry to say that this one is also not working.

command: "[all_registers]", return the list of all registers.

foreach_in_collection e [sort_collection [all_registers]] {
puts "[get_object_name $e]";
}

all_registers return a pointer then you need to return the name with get_object_name...

Hello RCA,

thank you very much.
This one is also not working in PrimeTime.

all_registers command working fine in dc_shell but not not working in PrimeTime.

What happened is :
current_design top_module
link -keep_sub_design
all_registers.

-> all_reg reports not a single cell.

Now,
current_design top_module
link -keep_sub_design
current_design sub_design_1
all_registers.

-> this all_reg list out the registers which are in sub_design_1.

But why not working when I set current design as a Top module in PrimeTime while its working fine in DC?

Please help me to solve problem.

Thanks in advance

Sorry mauln sheth,

foreach_in_collection e [sort_collection [all_registers]] {
puts "[get_object_name $e]";
}

but this code works with primetime, I used it to check if the reset pin of the registers is connected to the right reset generator.
