#1617 IR Drop Report, Unconnected PDN layer: 5 & 6 Issue created by Baungarten-CINVESTAV Description Hello, I am trying to integrate a small eFPGA (4 x 4 CLB) with Caravel, I have used OpenFPGA to create the FPGA architecture. The FPGA has been hardened and instantiated with Caravel, i just modify some variables of the caravel's config file (FP_PDN_MACRO_HOOKS, MACRO_PLACEMENT_CFG, VERILOG_FILES_BLACKBOX, EXTRA_LEFS, and EXTRA_GDS_FILES) How can I fix these errors?
