hi, I have an openram module inside my design, I excluded the verilog file from config.tcl and add macro parameters with: ### Macro PDN Connections set ::env(FP_PDN_MACRO_HOOKS) "\ sky130_sram_2kbyte_1rw1r_32x512_8 vccd1 vssd1" ### Macro Placement set ::env(MACRO_PLACEMENT_CFG) $script_dir/macro.cfg ### Black-box verilog and views set ::env(VERILOG_FILES_BLACKBOX) "\ $script_dir/../../verilog/rtl/rtl/components/sky130_sram_2kbyte_1rw1r_32x512_8.v" set ::env(EXTRA_LEFS) "\ $script_dir/../../lef/sky130_sram_2kbyte_1rw1r_32x512_8.lef" set ::env(EXTRA_GDS_FILES) "\ $script_dir/../../gds/sky130_sram_2kbyte_1rw1r_32x512_8.gds" after the design timing and area report openlane gave error by complaining: [INFO]: Performing Manual Macro Placement...

What are contents of 
$script_dir/macro.cfg
? You probably want the instance name from your verilog file instead of the module name here.
Copy code
set ::env(FP_PDN_MACRO_HOOKS) "\
   sky130_sram_2kbyte_1rw1r_32x512_8 vccd1 vssd1"

Thanks, You are right, but then I changed it and still got the same error now macro.cfg is: "open_ram_2k 590 370 N" and in config.tcl set ::env(FP_PDN_MACRO_HOOKS) "\ open_ram_2k vccd1 vssd1" and module instantiation is: sky130_sram_2kbyte_1rw1r_32x512_8 open_ram_2k( .clk0(clk), .csb0(1'b0), .web0(~(we_i & ~bypass_en_i)), .wmask0(be_i), .addr0(addr_i[10:2]), .din0(wdata_i), .dout0(ram_out_int), .clk1(1'b0), .csb1(1'b1), .addr1(9'b000000000), .dout1() );

Your module doesn't have any power connections.
How about at the gate level?
b
it was due to sv2v (systemverilog to verilog) conversion now I added powers thanks but does this cause macros not found error ?
m
Looking at the code, I don't think missing power connections will cause macro not found error. Is 
open_ram_2k
at the top level of your verilog?
b
no it is not, it is at the lower levels of hierarchy, may it be the reason? does a macro must be in the top level?
if it's the case, then i need to first select a new top module where openram is not in lower levels and harden this design then use this design to harden higher levels
m
That might be the quickest solution.
Maybe not the quickest. Looking through other macro.cfg files, I see hierarchical definitions
Copy code
qf105.qf100_qf100_spiCtrl

u_riscv_top.u_connect

microwatt_0.soc0.processor.execute1_0.multiply_0.multiplier
etc.
b
hmmm, worth try it, last hours on mpw6, i have no other chance 🙂
in which repo did u find it
m

👍 thanks a lot
i will try and share the result

hierarchial definitions work !!! Placing the following macros: {'pulpino_top.core_region_i.data_mem.open_ram_2k': ['590000', '370000', 'N'], 'pulpino_top.core_region_i.instr_mem.sp_ram_wrap_i.open_ram_2k': ['1630000', '370000', 'N']} Design name: pulpino_top_wrapper Placing pulpino_top.core_region_i.data_mem.open_ram_2k Placing pulpino_top.core_region_i.instr_mem.sp_ram_wrap_i.open_ram_2k Successfully placed 2 instances anyone using macros not on the top level can use this method
