It seems like old nets are kept in the database even if they are not in the new eco netlist. For example, I had a change that made this code: DTC23 \otpData_o_reg[spare2][0] (.Q(\otpData_o[spare2] [0]), .D(n_18), .CLRZ(p4), .CLK(clkTrim17Lo)); DTC23 \otpData_o_reg[spare2][1] (.Q(\otpData_o[spare2] [1]), .D(n_17), .CLRZ(p4), .CLK(clkTrim17Lo)); DTC23 \otpData_o_reg[spare2][2] (.Q(\otpData_o[spare2] [2]), .D(n_15), .CLRZ(p4), .CLK(clkTrim17Lo)); DTC23 \otpData_o_reg[spare2][3] (.Q(\otpData_o[spare2] [3]), .D(n_16), .CLRZ(FE_OFN235_porZ), .CLK(clkTrim17Lo)); Change to this: DTC23 \otpData_o_reg[spare2][0] (.Q(NVM_TRACKER_SEL), .D(n_18), .CLRZ(p4), .CLK(clkTrim17Lo)); DTC23 \otpData_o_reg[spare2][1] (.Q(NVM_BOOST_DIS), .D(n_17), .CLRZ(p4), .CLK(clkTrim17Lo)); DTC23 \otpData_o_reg[spare2][2] (.Q(NVM_SYS_ALT_SEL), .D(n_15), .CLRZ(p4), .CLK(clkTrim17Lo)); DTC23 \otpData_o_reg[spare2][3] (.Q(otpData_spare2_3), .D(n_16), .CLRZ(FE_OFN235_porZ), .CLK(clkTrim17Lo)); So, I am only changing the output net to a new name. When I do this, Encounter takes the old names (i.e. \otpData_o[spare2] [0]) and defines internal wires for them like this: wire \SPARE[19] ; wire \SPARE[20] ; wire \SPARE[21] ; wire \\otpData_o[spare2 ] [0] ; wire \\otpData_o[spare2 ] [1] ; wire \\otpData_o[spare2 ] [2] ; wire \\otpData_o[spare2 ] [3] ; The “\\” is keeping the database from saving. I get this error when trying to save: **ERROR: (ENCOAX-156): OA Exception : Input name (or member): \\otpData_o[spare2 ] [0] has improper bus syntax.. **ERROR: (ENCOAX-426): Error in creating EMH hierarchy. TIMER: oaOut total process: 0h 0m 0.05s cpu {0h 0m 0s elapsed} Memory = 0.0 **ERROR: (ENCIMEX-7323): Could not save design into OA database. Does anyone know a way to tell Encounter not to name it with \\ or how to remove the old physical wires from the database?? This is a postMask ECO, so I cannot re-synthesize. Thanks!
