Error in OL Magic GDSII Step - Multi errors on DEF file #2079

Closed mbaykenar closed 5 months ago

mbaykenar commented 6 months ago

Description

The flow crashes whenever I tried a macro hardening with the parameters:

set ::env(FP_PDN_CORE_RING) 0 set ::env(FP_PDN_MULTILAYER) 0

The fail happens in "Streaming out GDSII with KLayout" step.

If I set these parameters flow completes successfully.

Expected Behavior

A clear macro hardening flow is expected

After I changed power connections from 8 pins to 2 pins, where only digital powers are connected, the error has gone.

in top Verilog file:

`ifdef USE_POWER_PINS

vccd1,
vssd1,

`endif

in config.tcl file:

set ::env(VDD_NETS) "vccd1" set ::env(GND_NETS) "vssd1"

I am closing this issue since now I can harden macros.
