UPF Supply operating Voltage问题

BlakeLively

# ============================================================================
# UPF for TOP_B3 with Voltage Specifications
# Compatibility: Synopsys P-2019.03-SP5 (UPF 2.x style)
# Description:
#   - Two power domains:
#       * PD_A (Always-On) for TOP_B3
#       * PD_B (Power-Gated) for instance TOP_B3/I1/u_option
#   - Both domains operate at VDD_TOP = 1.5 V, common ground VSS = 0 V
#   - Power-down control: TOP_B3/I1/CTRL_PDB (active HIGH = power OFF PD_B)
#       * CTRL_PDB = 1 -> PD_B OFF
#       * CTRL_PDB = 0 -> PD_B ON
#   - Isolation on all signals from PD_B to PD_A, clamp to 0 when PD_B is OFF
#   - No level shifters needed (same voltage), no retention specified

check_mv_desgin 报错，显示没有设置电压，怎么折腾都不行，有没有大佬知道怎么解决。
UPF内最后加了这几句不起作用。
add_port_state VDD_A -state {ON 1.5}
#add_port_state PSW_B/out -state {ON 1.5 OFF 0.0} ---load_upf不识别PSW_B/out！！
#add_port_state VDD_B -state {ON 1.5 OFF 0.0}    --load_upf不识别VDD_B！！
add_port_state VSS     -state {ON 0.0}

Synopsys实现类工具要加set_voltage（不属于UPF命令）

感谢，解决了，在UPF里折腾了好久
